Participants

Reaction Steps

To the solution of 0.20 g (0.58 mmol) (R)-8-(1-isopropyl-piperidin-4-yloxy)-4-methyl-3,4-dihydro-2H-pyrazino[1,2-a]indol-1-one (example 8) in 3 mL N,N-dimethylformamide, 86 μg (0.64 mmol) N-chlorosuccinimide were added and the solution was stirred for 18 hours. The reaction mixture was poured on 1M aqueous sodium hydroxide solution and was extracted three times with ethyl acetate. The combined organic layers were washed with brine, dried over magnesium sulfate, filtered and evaporated. The crude product was purified by flash column chromatography on silica gel with dichloromethane:methanol:ammonia (9:1:0.1 v/v) as eluant to give 81 μg (37%) of the desired compound as a colorless oil.
