Reaction Steps

N-[(2RS,3SR)-2-(2-aminoethyl)-1-cyclohexylpiperidin-3-yl]-4-azepan-1-ylpyrimidin-2-amine (63 mg) was dissolved in dichloromethane (3 mL), PS-carbodiimide (327 mg) was added and then 0.5 M of a solution (0.47 mL) of 1-(tert-butoxycarbonyl)piperidine-4-carboxylic acid in dimethylformamide:dichloromethane=1:1 and 0.5 M of a mixture solution (0.53 mL) of hydroxybenzotriazole in dimethylformamide:dichloromethane=1:1 were added and stirred at room temperature for overnight. MP-carbonate (271 mg) was added into the reaction solution, stirred for 1 hour and then filtered and concentrated. The residue was purified by silica gel column chromatography (ethyl acetate:methanol=90:10) to obtain the title compound (81 mg) having the following physical properties.
