反応手順
The title compound was prepared by the procedure described in Example 10 using 17.7 g of 2-ethyl-6-methylphenyl-isothiocyanate, 18.4 g of N-ethyl glycine, 20.2 g of triethyl amine, and 300 mL of chloroform. The residue was further purified by flash chromatography on silica gel (20% ethyl acetate in hexane). The title compound was obtained (8.6 g) as a light peach solid, m.p. 82°-84° C. Anal. Calcd. for. C14H18N2OS: C, 64.09; H, 6.92; N, 10.68. Found: C, 64.27; H, 7.04; N, 10.60. Mass spectrum (EI, M.+) m/z 262.
