To a solution of 10,11-dihydro-5H-dibenz[b,f]azepine (2.44 g) in tetrahydrofuran (25 ml) was added potassium tert-butoxide (2.02 g) at 0° C. The mixture was stirred at 0° C. for 15 minutes, and then a solution of methyl 3-(chloromethyl)benzoate (3.57 g) in tetrahydrofuran (15 ml) was added. The mixture was stirred at 25° C. for 1 hour, and then evaporated. The residue was partitioned between ethyl acetate and 0.1N hydrochloric acid. The organic layer was washed with water and brine, dried over magnesium sulfate, and evaporated. The residue was chromatographed on silica gel eluting with a mixture of hexane and ethyl acetate (40:1) to give methyl 3-(10,11-dihydro-5H-dibenz[b,f]azepin-5-ylmethyl)benzoate (1.10 g) as an oil.
