실험 절차

A mixture of N-allyl glycine (17.4 g), 5-chloro-2-methylphenyl-isothiocyanate (20.1 g), triethylamine (20.2 g), and methylene chloride (150 mL) was heated at reflux for 2 hours. The reaction mixture was evaporated to dryness. Purification was achieved by flash chromatography on silica gel (methylene chloride). Recrystallization from Hexane-EtOAc afford the title compound (4.8 g) as yellow solid, m.p. 106°-109° C. Anal. Calcd. for. C13H13N2O Cl S: C, 55.61; H, 4.67; N, 9.98. Found: C, 55.45; H, 4.56; N, 9.72. Mass spectrum (EI, M.+) m/z 280.
