Reaction Steps

2-(3,4-Dichlorophenyl)-1-[(4aRS,8SR,8aRS)-8-(pyrrolidin-1-yl)-perhydroquinoxalin-1-yl]-ethan-1-one (100.9 mg, 0.25 mmol) was dissolved in absolute CH2Cl2 (13 ml) under a nitrogen atmosphere and methyl chloroformate (28.9 mg, 0.31 mmol) was added dropwise. The solution was stirred at room temperature for 2 hours. Thereafter, the mixture was evaporated in vacuo and the residue was purified by flash chromatography (Ø 2 cm, CH2Cl2/MeOH/NH3 9.5:0.5:0.05, l=16 cm, V=5 ml) and was obtained as a yellow resin.
