Reaction Conditions

Reaction Steps

To a solution of 0.30 g (0.91 mmol) of {(1R)-1-cyclohexylmethyl-2-[4-(2-methoxyphenyl)-piperazin-1-yl]-ethyl}-amine and 0.25 mL (1.74 mmol) of triethyl-amine in 10 mL of dichloromethane at 0° C. was added dropwise 0.16 g (1.00 mmol) of 1-methylcyclohexane-carboxylic acid chloride in 4 mL of dichloromethane. The reaction mixture was allowed to stir under nitrogen at 0° C. for one hour, and was then concentrated on a rotary evaporator, diluted with ethyl acetate and washed with saturated aqueous NaHCO3 and brine. The organic phase was dried over anhydrous sodium sulfate, filtered and concentrated on a rotary evaporator to yield the crude product, which was purified by flash chromatography on silica gel (dichloromethane/methanol) and then converted to the hydrochloride·hydrate salt of the title compound with ethanolic HCl to yield 0.30 g (63%) of a light yellow solid; mp=119-121° C.; MS (+) ESI m/z=456 (M+H)+.
