Versuchsvorschrift

To anhydrous acetic acid (0.2 ml) was added dropwise formic acid (0.1 ml), under ice-cooling, and the mixture was heated to stir under nitrogen atmosphere at 50° C. for 2 hours. To the mixture was added THF (5 ml), and then to the mixture was added dropwise, under ice-cooling, a solution of methyl 7-(4-morpholinophenyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.3 g) in THF (15 ml). The mixture was stirred at room temperature for 1.5 hours. The solvent was evaporated, and to the residue was added water. The mixture was extracted with ethyl acetate. The organic layer was washed with sodium hydrogen carbonate solution, water and saturated brine, and dried with anhydrous magnesium sulfate, and the solvent was evaporated to give methyl 1-formyl-7-(4-morpholinophenyl)-2,3-dihydro-1H-1-benzazepine-4-carboxylate (0.3 g) as pale yellow crystals.
