Reaction Steps

A mixture of 4-amino-2-(morpholin-4-yl)-1,3-thiazole-5-carboxamide (0.22 g, 0.98 mmol; prepared according to Liebigs Annalen der Chemie, 1986, 4, 780-4), 2,2-dimethoxypropane (3 mL, excess), acetone (2 mL, excess) and p-toluenesulfonic acid monohydrate (cat. amount) was heated to 100° C. in a sealed tube, under microwave irradiation, for 1 h. The reaction mixture was then concentrated in vacuo and purification by preparative HPLC gave the title compound (0.04 g, 16%) as an off-white solid. δH (DMSO-d6) 7.54 (1H, s), 7.01 (1H, s), 3.73-3.63 (4H, m), 3.49-3.38 (4H, m), 1.38 (6H, s). LCMS (ES+) 269.0 (M+H)+.
