Participants

Reaction Steps

1-Methyl-4-(8-methylimidazo[1,5-a]pyrazin-3-yl)pyrrolidin-2-one (293 mg, 1.27 mmol) was dissolved N,N-dimethylformamide (12 ml) and N-bromosuccinimide (227 mg, 1.27 mmol) was added and reation mixture was stirred at room temperature overnight. Then water was added to the reaction mixture and extracted with chloroform/iso-propanol (9/1) three times. The combined organic layers were dried (Na2SO4) and concentrated in vacuo and a brown oil was obtained. The residue was purified by column chromatography (silica gel; dichloromethane/methanol/heptane=9/1/4) to give 4-(1-bromo-8-methylimidazo[1,5-a]pyrazin-3-yl)-1-methylpyrrolidin-2-one (200 mg).
