The title compound, C20H17N3OS, is a 1H-pyrazol-3(2H)-one having aromatic 4-(1,3-benzothia­zol-2-yl)- and 2-phenyl substituents. The five-membered ring and fused ring system are planar, the r.m.s. deviations being 0.021 and 0.005 Å, respectively. The five-membered ring is aligned at 7.9 (2)° with respect to the fused-ring system. The allyl and phenyl parts of the mol­ecule are both disordered over two positions in a 1:1 ratio. Weak inter­molecular C—H...O hydrogen bonding is present in the crystal structure.

Comment top

(E)-4-(2,3-Dihydro-1,3-benzothiazol-2-ylidene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one is an amine that can under a nucleophilic substitution with organo bromides to form 2-substituted derivatives if tetra-n-butyl ammonium bromide is used as catalyst. In this study, the compound is reacted with allyl bromide to yield the title compound (Scheme I, Fig. 1).

Experimental top

To a solution of (E)-4-(2,3-dihydro-1,3-benzothiazol-2-ylidene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one (1 g, 3.25 mmol) in DMF (50 ml), was added sodium carbonate (2.5 g, 23 mmol), tetra-n-butyl ammonium bromide (0.15 g, 1 mmol) and allyl bromide (5.6 g, 46 mmol). The mixture was stirred for 24 h at room temperature. The solid material was removed by filtration and the solution was evaporated under reduced. The residue was washed with dichloromethane and hexane, and the recrystallized from ethanol to afford the title compound as colorless crystals.

Refinement top

Carbon-bound H-atoms were placed in calculated positions (C—H 0.93–0.97 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2–1.5Ueq(C).

The allyl and phenyl units are disordered over two positions; the disorder could be refined, and was assumed to be a 1:1 type of disorder. For the allyl unit, the single-bond distances were restrained to 1.50±0.01 Å and the double-bond distances to 1.35±0.01 Å; the anisotropic temperature factors were restrained to be nearly isotropic. The phenyl rings were refined as rigid hexagons of 1.39 Å sides; the N–Cphenyl pair of distances were restrained to within 0.01 Å of each other. Additionally, the temperature factors of the primed atoms were restrained to those of the unprimed ones.
