Methanesulfonyl chloride → HCID 178505139, compound

Participants

Reaction Steps

To a stirred mixture of Trans-4-[2-(4-Benzo[1,3]dioxol-4-yl-piperidin-1-yl)-ethyl]-cyclohexylamine hydrochloride (intermediate A) (30 mg, 0.0818 mmol, Eq: 1.00) in dichloromethane (500 μl) was added at room temperature N,N-diisopropylethylamine (31.6 mg, 42.7 μl, 245 μmol, Eq: 3) and methanesulfonyl chloride (14.1 mg, 123 μmol). The mixture was allowed to stir at room temperature over night. The crude reaction diluted with 5 mL sat NaHCO3 and extracted with DCM (2×10 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 10% MeOH in DCM) to yield the title compound as an white solid (16.2 mg, 48.5%), MS (ISP) m/z=409.3 [(M+H)+].
