A mixture of N-butyl glycine (12.0 g), 5-chloro-2-methylphenyl-isothiocyanate (9.15 g), triethyl amine (12.0 g) and chloroform (200 mL) was heated at reflux for 5 hours. The solvent was evaporated. The residue was treated with diethyl ether (400 mL). The mixture was filtered. The solid was washed with diethyl ether then discarded. The filtrate was evaporated to dryness. Crystallization from ethanol afforded the title compound (6.0 g) as a tan solid, m.p. 102°-103° C. Anal. Calcd. for. C14H17Cl N2 O S: C, 56.65; H, 5.77; N, 9.44. Found: C, 56.41; H, 5.97; N, 9.36. Mass spectrum (EI, M.+) m/z 296/298.
