Reaction Steps

A 40 mL vial was charged with a magnetic stirring bar, 3-(4-aminophenyl)-5-morpholino-7H-thieno[3,2-b]pyran-7-one (56) (200 mg, 609 μmol) and pyridine (5 mL). The mixture was magnetically stirred and cooled to 0° C. in an ice bath. Isonicotinoyl chloride hydrochloric acid (669 μmol) was added and the reaction was stirred at room temperature for 30 minutes. The reaction was diluted with dichloromethane (15 mL) and washed three times with saturated aqueous sodium bicarbonate solution (15 mL). The dichloromethane layer was dried over magnesium sulfate, filtered, and concentrated in vacuo to give N-(4-(5-morpholino-7-oxo-7H-thieno[3,2-b]pyran-3-yl)phenyl)nicotinamide (30) (94 mg, 217 μmol) as a yellow solid.
