Procedure
To a solution of 0.82 g (4 mmol) of 5H,7H-dibenzo[b,d]azepin-6-one in 15 ml of dimethylformamide at room temperature 0.20 g (5 mmol) of sodium hydride 55% in oil was added. After stirring for 30 min at room temperature 0.75 g (5 mmol) of p-methoxybenzyl chloride were added and stirring was continued at room temperature for 2 hours. For workup the mixture was distributed between water and ethyl acetate. The organic layer was re-extracted with 1 N hydrochloric acid and the aqueous layers were washed with ethyl acetate. The combined organic layers were dried (MgSO4) and concentrated in vacuo. The residue was purified by column chromatography (hexane/ethyl acetate=1:1) to yield 1.175 g (91%) of 5-(4-methoxybenzyl)-5H,7H-dibenzo[b,d]azepin-6-one as a colourless oil; MS: m/e: 330.4 (M+H+).
