Participants

Reaction Steps

In 10 ml of dichloromethane was dissolved 1.50 g of 1-(3-acetyl-2,3,4,5-tetrahydro-1H-3-benzazepin-7-yl)-2-chloro-1-ethanone obtained in Reference Example 2. To the solution was added 1.7 ml of piperidine, and the mixture was stirred for one hour at room temperature. The reaction mixture was poured into an aqueous solution of potassium carbonate, which was subjected to extraction with dichloromethane. The extract was dried over anhydrous sodium sulfate, from which was distilled off the solvent to leave an oily residue. To the residue was dissolved in 5 ml of methanol, to which was added 1.7 ml of 4N methanolic hydrochloric acid. Then the solvent was distilled off to leave 1.50 g of the title compound as colorless powder.
