Participants

Reaction Steps

A 100 mL round bottom flask was charged with N-(2,5-dioxo-3,4-dihydro-1H-benzo[b]azepin-3-yl)-3-(2,4-dichlorophenyl)-propionamide (2.5 g, 6.38 mmole), potassium carbonate (1.76 g, 12.7 mmole), DMF (20 mL), and iodomethane (3.55 g, 25 mmole). The reaction mixture was stirred at room temperature for 5 hr. and then poured into saturated sodium bicarbonate (500 mL). The aqueous mixture was extracted with ethyl acetate (3×200 mL). The combined organics were dried over anhydrous magnesium sulfate, filtered, and concentrated at reduced pressure. The resulting solid was swished with a minimum of warm ether and filtered to give 2.1 g (81%) of the product. mp 182°-184° C.
