The title compound was prepared by the procedure described in Example 19 using 9.2 g of N-ethyl glycine, 9.1 g of 2-chloro-6-methylphenyl-isothiocyanate, 10.1 g of triethylamine, and 150 mL of methylene chloride. Purification was achieved by flash chromatography on silica gel (methylene chloride). Crystallization from ethanol afforded the title compound (5.4 g) as a creamy solid, m.p. 124°-126° C. Anal. Calcd. for. C12H13Cl N2O S: C, 53.63; H, 4.87; N, 10.42. Found: C, 53.43; H, 4.79; N, 10.28. Mass spectrum (El, M.+) m/z 268/270.
