Reaction Steps
A mixture of N-(4-chlorobenzyl)-2-(chloromethyl)-4-methyl-7-oxo-4,7-dihydrothieno[3,2-b]pyridine-6-carboxamide (50 mg, 0.13 mmol), morpholine (17.4 mg, 0.20 mmol) and diisopropylethylamine (35 μL, 0.20 mmol) in dry DMF (2.7 mL) was heated to 60° C., becoming a solution. The reaction was stirred for 3 hours at that temperature. After cooling to room temperature, the solution was diluted with water (5 mL). The resulting milky suspension was stirred vigorously for 30 minutes, and then left standing overnight at room temp. The mixture was filtered, and the collected solid was washed with water and dried in vacuo, leaving a white solid. Recrystallization from acetonitrile (10 mL) gave the title compound (48 mg) as a flocculent white solid.
