Reaction Conditions

Reaction Steps

The title compound was prepared from Trans-4-[2-(4-Benzo[1,3]dioxol-4-yl-piperazin-1-yl)-ethyl]-cyclohexylamine hydrochloride (Intermediate A) (25 mg, 0.068 mmol) and triethylamine (20.6 mg, 28.4 μl, 204 μmol) in dichloromethane (1 mL). Methyl carbonochloridate (7.06 mg, 5.78 μl, 0.075 μmol) was added to the mixture stirring at 0° C. The ice bath was removed and the reaction mixture was stirred for 1 hour at room temp. The reaction was diluted with dichloromethane and quenched with sat NaHCO3 (4 mL). The aqueous layer was extracted with DCM (1×5 mL). The organic layers were dried over MgSO4 and concentrated in vacuo. The crude material was purified by flash chromatography (silica gel, 10 g, 0% to 15% MeOH in dichloromethane) to yield the title compound as a white solid (9 mg, 34%), MS (ISP) m/z=390.3 [(M+H)+].
