A mixture of N-ethyl glycine (9.2 g), 2,6-dimethylphenyl-isothiocyanate (8.2 g), triethylamine (10.1 g), and methylene chloride (150 mL) was heated at reflux for 3.5 hours. The mixture was evaporated to dryness. Purification was achieved through crystallization from ethanol. The title compound (2.3 g) was obtained as a white solid (2.3 g). m.p. 128°-131° C. Anal. Calcd. for. C13H16N2OS: C, 62.87; H, 6.49; N, 11.28. Found: C, 62.83; H, 6.50; N, 11.25. Mass spectrum (EI, M.+) m/z 248.
