Reaction Steps

To a mixture of 4-chloro-5,7-dihydro-pyrrolo[2,3-d]pyrimidin-6-one (85 mg, 0.5 mmol) and 3,5-dimethyl-4-(3-morpholin-4-yl-propyl)-1H-pyrrole-2-carbaldehyde (125 mg, 0.5 mmol) in ethanol (4 mL) was added 0.1 to 0.2 mL of piperidine. The mixture was stirred at room temperature for 20 hours. The yellow precipitate was filtered after cooled with an ice bath, washed with cold ethanol, and dried to give 89 mg (45%) of 4-chloro-5-[3,5-dimethyl-4-(3-morpholin-4-yl-propyl)-1H-pyrrol-2-ylmethylene]-5,7-dihydro-pyrrolo[2,3-d]pyrimidin-6-one.
