Reaction Steps

To a solution of (E)-3-[5—(4-methylphenyl)pyridin-3-yl]acrylic acid (150 mg), 4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]aniline (168 mg) and triethylamine (0.10 ml) in DMF (10 ml) was added diethyl cyanophosphate (0.12 ml) at 0° C., and the mixture was stirred at room temperature for 3 hours and concentrated under reduced pressure. To the residue was added water, the mixture was extracted with chloroform. The organic layer was washed with saturated sodium chloride solution, dried with magnesium sulfate and concentrated under reduced pressure. The residue was separated and purified with column chromatography (ethanol/ethyl acetate=1:2) to give (E)-N-[4-[N-methyl-N-(tetrahydropyran-4-yl)aminomethyl]-phenyl]-3-[5—(4-methylphenyl)pyridin-3-yl]acrylic amide (Compound 215) (24 mg) as yellow solid. 1H-NMR (200 MHz, CDCl3) δ 1.66-1.83 (4H, m), 2.21 (3H, s), 2.43 (3H, s), 2.53-2.74 (1H, m), 3.30-3.45 (2H, m), 3.57 (2H, s), 3.99-4.10 (2H, m), 6.69 (1H, d, J=15.5 Hz), 7.24-7.37 (4H, m), 7.41-7.63 (5H, m), 7.82 (1H, d, J=15.5 Hz), 7.95-8.01 (1H, m), 8.74 (1H, d, J=1.8 Hz), 8.81 (1H, d, J=2.2 Hz).
