To a solution of 2-[2-(2-thienylcarbonyl)-1H-pyrrol-1-yl]-1H-isoindole-1,3(2H)dione (15.43 g) in 50 ml of dimethylformamide was added 50 ml of 40% methylamine. The reaction mixture was stirred for 1.5 hours at room temperature, diluted with water and extracted with DCM. The combined organic layers were washed with water, dried over magnesium sulfate and evaporated in vacuo. The residual oil was recrystallized from ethyl ether/hexane to afford the product (5.96 g), m.p. 81°-82° C.
