Participants

Reaction Steps

A mixture of 8-(2-bromo-4-isopropyl-phenyl)-4-chloro-2-methyl-pyrrolo[1,2-a]pyrimidine-6-carbonitrile (300 mg), 1-propyl-butylamine (267 mg), N,N-diisopropylethylamine (300 mg) in ethanol (1.0 mL) was heated at reflux overnight. The reaction mixture was cooled to room temperature, poured into a saturated aqueous sodium hydrogencarbonate, and then extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated under reduced pressure and purified by a silica gel column chromatography (silica gel: Wako Gel (C200), eluent: hexane/ethyl acetate=20:1) to give 8-(2-bromo-4-isopropyl-phenyl)-2-methyl-4-(1-propyl-butylamino)-pyrrolo[1,2-a]pyrimidine-6-carbonitrile (321 mg) as a pale brown solid.
