Reaction Steps

A mixture of 1,3-dihydroindol-2-one (133 mg, 1.0 mmol), 3,5-dimethyl-4-(3-morpholin-4-yl-propyl)-1H-pyrrole-2-carboxaldehyde (250 mg, 1.0 mmol) and 3 drops pyrrolidine in 2.0 ml of ethanol was refluxed at 90° C. for 4 hours and then cooled to room temperature. The precipitate was filtered, washed with cold ethanol and hexane, and dried in a vacuum oven overnight to give 308.9 mg (85%) of 3-[3,5-dimethyl-4-(3-morpholin-4-yl-propyl)-1H-pyrrol-2-ylmethylene]-1,3-dihydroindol-2-one as a yellow solid:
