Procedure

To a solution of 0.2 g (0.66 mmol) of {(1R)-1-cyclohexylmethyl-2-[4-(pyrimidin-2-yl)-piperazin-1-yl]-ethyl}-amine and 0.18 mL (1.32 mmol) of triethylamine in 10 mL of dichloromethane at 0° C. was added dropwise 0.082 g (0.69 mmol) of cyclobutanecarboxylic acid chloride in dichloromethane (2 mL). The reaction mixture was allowed to stir under nitrogen for two hours at 0° C. and was then concentrated on a rotary evaporator, diluted with ethyl acetate and washed with H2O 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 converted to the hydrochloride salt of the title compound with ethereal HCl to yield 0.18 g (62%) as a white solid; mp=112–114° C.; MS (+) ESI m/z=386 (M+H)+.
