HCID 223292217-[4-[N-(2-ethoxyethyl)-N-methylamino]phenyl]-1-formyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide

実験手順

In DMF (3.5 ml) was dissolved 7-[4-[N-(2-ethoxyethyl)-N-methylamino]phenyl]-1-formyl-2,3-dihydro-1H-1-benzazepine-4-carboxylic acid (0.17 g). To the solution was added, under ice-cooling, thionyl chloride (0.08 ml), and the mixture was stirred at room temperature for 30 minutes. Under reduced pressure, the solvent was evaporated, and the residue was dissolved in THF (25 ml). The solution was added dropwise to a solution of 4-[N-methyl-N-(tetrahydro-2H-pyran-4-yl)aminomethyl]aniline (0.11 g) and triethylamine (0.31 ml) in THF (6.5 ml), under ice-cooling, and the mixture was stirred under nitrogen atmosphere at room temperature for 1 hour, poured into water and extracted with ethyl acetate. The organic layer was washed with water and saturated brine and dried with anhydrous magnesium sulfate, and the solvent was evaporated. The residue was purified with silica gel column chromatography (ethyl acetate/ethanol) to give crude crystals, which were recrystallized from ethanol to give 7-[4-[N-(2-ethoxyethyl)-N-methylamino]phenyl]-1-formyl-N-[4-[[N-methyl-N-(tetrahydro-2H-pyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1H-1-benzazepine-4-carboxamide (Compound 4) (0.14 g) as pale yellow crystals.
