7-Benzyloxy-3-cyclobutyl-2,3,4,5-tetrahydro-1H-benzo[d]azepine (E1) (9.22 g, 30 mmol) was dissolved in ethanol (150 ml) and tetrahydrofuran (50 ml). Palladium (1.5 g, 10% on charcoal paste) was added and the reaction mixture was stirred at room temperature under hydrogen (1 atmosphere) for 5 hours. The reaction mixture was filtered through celite and the filtrate concentrated in vacuo. The crude residue was triturated with diethyl ether and filtered to afford the title product (E3); MS (ES+) m/e 218 [M+H]+.
