Procedure

One droplet of DMF was added to a solution of 7-(4-butoxyethoxyphenyl)-1-(2-fluorobenzyl)-2,3-dihydro-1-benzazepine-4-carboxylic acid (200 mg) in tetrahydrofuran (10 ml). Then, thionyl chloride (146 mg) was added at 0° C., the temperature was returned to room temperature, and the mixture was stirred under nitrogen atmosphere for 1 hour. The solvent and excess thionyl chloride were evaporated under reduced pressure, the resulting residue was suspended in tetrahydrofuran (30 ml), and the suspension was added to a solution of 4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]aniline (108 mg) and triethylamine (496 mg) in tetrahydrofuran (10 ml) at 0° C. The suspension was stirred under nitrogen atmosphere at room temperature overnight, to the mixture was added water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried with magnesium sulfate. The solvent was evaporated under reduced pressure, the resulting residue was separated and purified with silica gel column chromatography (methanol:ethyl acetate=1:8) to give 7-(4-butoxyethoxyphenyl)-1-(2-fluorobenzyl)-N-[4-[[N-methyl-N-(tetrahydropyran-4-yl)amino]methyl]phenyl]-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 66) (139 mg) as yellow amorphous.
