Participants

Reaction Steps

To a solution of 7—(4-pyridyl)-2,3-dihydro-1-benzoxepine-4-carboxylic acid (0.15 g), 4—(N-methyl-N-(tetrahydropyran-4-yl)aminomethyl)aniline (0.12 g) and triethylamine (0.16 ml) in dimethylformamide (50 ml)was added diethyl cyano-phosphate (0.1 ml) under ice-cooling, and the mixture was stirred under nitrogen atmosphere at room temperature over night. The solvent was evaporated, and the residue was purified with silica gel column (methanol/ethyl acetate/triethylamine) to give crude crystals, which were recrystallized from ethanol-hexane to give 7—(4-pyridyl)-N-(4—((N-tetrahydropyran-4-yl-N-ethylamino)methyl)phenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (Compound 147) (0.07 g) as pale brown crystals.
