The title compound, C15H17ClNO2S+·C10H15O4S−·C3H6O, was synthesized by N-alkylation of α-amino-(2-chlorophenyl)acetate with 2-thienylethyl p-toluenesulfonate, followed by reaction with (+)-camphor-10-sulfonic acid. In the crystal, the cations and anions are linked through N—H⋯O hydrogen bonds. The thiophene ring of the cation was found to be disordered over two sites, with refined occupancies of 0.798 (4) and 0.202 (4).

(I) was prepared according to the method of Descamps & Radisson (1992). 12.5 g of methyl alpha-amino(2-chlorophenyl)acetate was released from its hydrochloride by reaction with 9 g of NaHCO3 in the presence of 200 ml of CH2Cl2 and 65 ml of water. The resulting amine was dissolved in 65 ml of acetonitrile; 6.2 g of NaHCO3 and 15.6 g of 2-thienylethyl-para-toluenesulfonate were then introduced; the mixture was kept at 353 K for 22 h and the volatile products were then evaporated off under reduced pressure. The residue was dissolved in 200 ml of ethyl acetate and 65 ml of water; the organic phase was separated off. After the usual treatments the aminoester was obtained and dissolved in 70 ml of acetone, then 8.7 g of (+)-10-camphorsulfonic acid was introduced. The mixture was stirred at room temperature for 12 h to get precipitate, and 11 g of camphorsulfonate was thus obtained. The camphorsulfonate was suspended in 50 ml of refluxing acetone and 25 ml of methyl ethyl ketone to obtain complete dissolution. The mixture was standing under 298 K, then white crystals were grown slowly. The crystals were washed with cold acetone, yield 6.8 g, m.p. 368 K.
2828 Friedel pairs were used in the ═C) = 1.34 Å, respectively. Ammonium H atoms were initially located in a difference map and refined with the restraints N—H = 0.85 (2) Å. Other H atoms were positioned geometrically and refined using a riding model, with d(C—H) = 0.93–0.98 Å and Uiso(H) = 1.2Ueq(C) or 1.5Ueq(Cmethyl).
The thiophene ring was found to be disordered and was refined with the restraints d(C—S) = 1.72 Å, d(C—C) = 1.50 Å and d(CClopidogrel treatment is associated with a reduction in thrombotic complications in coronary stent placement, improved outcome after acute coronary syndromes, and decreased mortality in patients with coronary artery disease (Kang et al., 2007). Now, we present the
of the title compound, (I), an intermediate of Clopidogrel (Fig. 1, Table 1).All bond lengths and angles in (I) are within normal ranges (Bruno et al., 2004). In the cation, C5 to C9, N1, O1 and O2 are almost coplanar (r.m.s. deviation 0.0363 Å and maximum deviation 0.0610 (2) Å). In the anion, the dihedral angles formed between C17 to C20 plane and C17/C20/C21 plane, C17/C20/C21 plane and C17/C20/C24/C25 plane are 54.45 (2)° and 54.47 (3)°, respectively. The crystal is stabilized by N—H···O hydrogen bonds between the cations and the anions, which link the molecules into sheets in the bc plane (Fig. 2, Table 2).

Clopidogrel treatment is associated with a reduction in thrombotic complications in coronary stent placement, improved outcome after acute coronary syndromes, and decreased mortality in patients with coronary artery disease (Kang et al., 2007). Now, we present the crystal structure of the title compound, (I), an intermediate of Clopidogrel (Fig. 1, Table 1).
All bond lengths and angles in (I) are within normal ranges (Bruno et al., 2004). In the cation, C5 to C9, N1, O1 and O2 are almost coplanar (r.m.s. deviation 0.0363 Å and maximum deviation 0.0610 (2) Å). In the anion, the dihedral angles formed between C17 to C20 plane and C17/C20/C21 plane, C17/C20/C21 plane and C17/C20/C24/C25 plane are 54.45 (2)° and 54.47 (3)°, respectively. The crystal is stabilized by N—H···O hydrogen bonds between the cations and the anions, which link the molecules into sheets in the bc plane (Fig. 2, Table 2).
