Versuchsvorschrift

To a solution of N-(4-chloromethylphenyl)-7-(4-ethoxyphenyl)-2,3-dihydro-1-benzoxepine-4-carboxamide (2.38 g) in DMF (20 ml) was added N,N-dimethyl-N-tetrahydropyran-4-ylamine (1.42 g) at room temperature, and the mixture was stirred for 14 hours. To the reaction mixture was added ethyl acetate (100 ml) to precipitate crystals, which were collected by filtration. The crystal was washed with ethyl acetate to give crude product as pale yellow crystals, which were recrystallized from ethanol to give as N-(4-(((7-(4-ethoxyphenyl)-2,3-dihydro-1-benzoxepin-4-yl)carbonyl)amino)benzyl)-N,N-dimethyl-N-(4-tetrahydropyranyl)ammonium chloride (Compound 250) (1.29 g) colorless crystals.
