Participants

Reaction Steps

To a stirred mixture of trans-4-{2-[4-(2,3-dihydrofuro[3,2-c]pyridin-4-yl)-piperazin-1-yl]-ethyl}-cyclohexanamine trihydrochloride (intermediate C) (110 mg, 0.25 mmol) in dichloromethane (1.6 ml) was added at room temperature triethylamine (139 mg, 192 μl, 1.38 mmol) and methanesulfonyl chloride (43.0 mg, 29.2 μl, 375 μmol). The mixture was allowed to stir at room temperature for 4 h, poured into ice/water (5 ml) and 1N sodium hydroxide solution (5 ml) and extracted with dichloromethane (2×20 ml). The combined organic layers were washed with brine (20 ml), dried (MgSO4) and evaporated. The crude material (0.1 g) was triturated with dichloromethane (1 ml) and heptane (5 mL) for 30 min. The precipitate was collected by filtration, washed with heptane and dried to yield the title compound as a white solid (90 mg, 88%), MS (ISP) m/z=409.4 [(M+H)+], mp 220° C.
