Procedure

To a mixture of diethyl 2-(((2-(morpholin4-ylmethyl)-1,3-thiazol-5-yl)amino)-methylene)malonate (Preparation 28, 1.51 g) and K2CO3 (1.19 g) in DMF (15 mL) at ambient temperature is added iodomethane (0.28 mL). The mixture is heated to 75° C. in a sealed pressure tube and stirred overnight. The solution is cooled to ambient temperature and the solvent is removed. The mixture is diluted with water (75 mL) and extracted with EtOAc (3×75 mL). The organic layer is dried (MgSO4) and the solvent removed to afford 0.984 g (63%) of the title compound as a light brown solid. Physical characteristics: 1H NMR (CDCl3) δ 1.24-1.33, 2.60, 3.31, 3.74, 4.17-4.24, 7.60; IR (liq.) 1702, 1608, 1535, 1453, 1383, 1365, 1293, 1270, 1232, 1206, 1117, 1096, 1071, 1010, 865 cm−1; HRMS (FAB) m/z 384.1600 (C17H25N3O5S+H). Anal. Found: C, 53.18; H, 6.64; N, 10.41.
