Procedure
Into a suspension of (E)-3-[5-(4-methylphenyl)pyridin-3-yl]acrylic acid (150 mg) and 1-hydroxybenzotriazole (134 mg) in acetonitrile (15 ml) was added at room temperature 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (0.19 g), and the resulting mixture was stirred for 2 hours. Into the reaction mixture was added a solution of trans-4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]cyclohexylamine dihydrochloride (198 mg), 1,8-diazabicyclo[5,4,0]-7-undecene (0.2 g) and triethylamine (0.18 ml) in acetonitrile (20 ml), and the resulting mixture was stirred for 64 hours. After the reaction mixture was concentrated under reduced pressure, water was added to the residue, and the resulting mixture was extracted with chloroform. The organic layer was washed with an aqueous saturated solution of sodium chloride and was dried with magnesium sulfate. After the resulting organic layer was concentrated under reduced pressure to remove the solvent, the precipitated crystals were purified by recrystallization (ethanol/ethyl acetate) to obtain (trans, E)-3-[5-(4-methylphenyl)pyridin-3-yl]-N-[4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]cyclohexyl]acrylamide (compound 73) (226 mg) as colorless crystals.
