(Received 6 June 2013; accepted 25 June 2013; online 29 June 2013)

In the title compound, C14H15BrN2O2S, synthesized by the reaction of the corresponding phenacyl thio­cyanate with morpholine, the dihedral angle between the 1,3-thia­zole ring and the phenolic substituent ring is 23.46 (10)° as a result of the steric influence of the ortho-methyl group on the thia­zole ring. A strong intra­molecular phenolic O—H⋯N hydrogen bond is present in the mol­ecule. In the crystal, a weak C—H⋯Ophenol hydrogen bond gives rise to chains lying parallel to [20-1]. A short inter­molecular Br⋯Omorpholine inter­action is also present [3.1338 (19) Å].

Comment top

Many derivatives of thiazole exhibit pharmacological activities (Coco & Onnis, 1993; Zagade & Senthilkumar, 2011)) and some of them are used as chemotherapeutic agents with anti-inflammatory, analgesic and antipyretic activities (Tanaka et al., 1994). Recently, 2-aminothiazoles were described as a new class of small molecules with antiprion activity in prion-infected neuroblastoma cell lines (Ghaemmaghami et al., 2010). On the other hand, thiocyanates play an important role in the chemistry of organosulfur compounds (Gewald et al., 1994). Among these alkyl 2-thiocyanato phenylketones there are versatile precursors for various substituted thiazoles (Zimmermann et al., 1990). The title compound, C14H15BrN2O2S, has been synthesized by the reaction of 1-(5-bromo-2-hydroxyphenyl)-2-thiocyanatopropan-1-one with morpholine and the structure is reported herein. In this compound (Fig. 1), although an intramolecular hydrogen bond is present between the phenolic O1—H group and N1 of the thiazole ring (Table 1), the benzene and thiazole rings are not coplanar, with a dihedral angle of 23.46 (10) ° between them. The steric influence of the methyl substituent group in the 5-position of the thiazole ring is considered to be responsible for this deviation. In the crystal, only a weak intermolecular C9—H···O1i (phenol) hydrogen-bonding association is present, giving a one-dimensional chain lying parallel to [2 0 -1], while a short Br···O2ii (morpholine) interaction [3.1338 (19) Å] is also found [for symmetry code (ii): x -1, -y + 1/2, z +1/2].

Experimental top

A mixture of 1-(5-bromo-2-hydroxyphenyl)-2-thiocyanatopropan-1-one (0.3 mmol) and morpholine (0.45 mmol) in 50 ml of methanol was heated under reflux for 20 min (Seliger et al., 1997). After 24 h the reaction mixture was poured into water and the precipitate filtered off and dried. Recrystallization from methanol gave the pure product as colorless crystals, m.p. 415 K.

Refinement top

The C-bound H-atoms were included at calculated positions and treated using a riding model, with aromatic C—H = 0.95 Å and methylene C—H = 0.99 Å, and with Uiso(H) = 1.2Ueq(C), or with methyl C—H = 0.98 Å, with Uiso(H) = 1.5Ueq(C). The phenolic H-atom (H1) was freely refined.

Special details top

Experimental. Absorption correction: interpolation using International Tables Vol C, Table 6.3.3.3 for values of muR in the range 0-2.5, and International Tables Vol. II, Table 5.3.6 B for µR in the range 2.6-10.0. The interpolation procedure (Dwiggins, 1975) is used with some modification.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
