Participants

Reaction Steps

The title compound was prepared by the procedure described in Example 6 using 12.9 g of 2-[3-(2-chloro-6-methylphenyl)-thioureido]-acetamide, and 18.0 g of ethyl iodide. The hydrochloride salt was prepared in ethereal hydrogen chloride. Crystallization from ethyl acetate afforded the title compound as the mono-hydrochloride as a light yellow solid (4.9 g), m.p. 152°-154° C. (dec.). Anal. Calcd. for. C12H13Cl N2O S . HCl: C, 47.22; H, 4.62; N, 9.18. Found: C, 46.99; H, 4.60; N, 9.16. Mass spectrum (+FAB, [M+H]+) m/z 269/271. 1H-NMR (DMSO-d6 ; 400 MHz) δ8.28 (broad s, 2 H), 7.51 (m, 1 H), 7.44 (t, 1 H), 7.39 (m, 1 H), 4.51 (q, 2 H), 3.12 (q, 2 H), 2.17 (s, 3 H), and 1.27 ppm (t, 3 H).
