実験手順
A solution of 70 mg (0.23 mmol) of 7-(3-fluoro-benzyloxy)-2,3,4,5-tetrahydro-1H-benzo[d]azepine hydrochloride [Example 1c)] in 1 ml of acetone was successively treated with 69 mg (0.5 mmol) of potassium carbonate and 24 mg (0.25 mmol) of 2-chloroacetamide. The reaction mixture was heated to reflux during 18 h. For the working-up, 1 g of silica gel was added to the cooled reaction mixture, which was then evaporated under reduced pressure. For purification, the crude material obtained was chromatographed on silica gel using a 95:5:0.1-mixture of dichloromethane, methanol and ammonium hydroxide as the eluent. There were obtained 38 mg (51% of theory) of 2-[7-(3-fluoro-benzyloxy)-1,2,4,5-tetrahydro-benzo[d]azepin-3-yl]-acetamide as a white solid; MS: m/e 329 (M+H)+.
