Procedure

Under N2, 2-(3,4-dichlorophenyl)-1-[(4aRS,8SR,8aRS)-8-(pyrrolidin-1-yl)-perhydroquinoxalin-1-yl]-ethan-1-one (113 mg, 0.29 mmol) was dissolved in absolute CH2Cl2 (14 ml) and acetyl chloride (27 mg, 0.34 mmol) was added dropwise. The mixture was stirred at room temperature overnight and then evaporated in vacuo. The residue was purified by flash chromatography (Ø 2 cm, CH2Cl2/MeOH/NH3 9.5:0.5:0.05, l=15 cm, V=5 ml). A yellowish resin was obtained.
