Procedure

To a solution of trans-2,2,2-trifluoro-N-[2,3,4,14b-tetrahydro-7-[(phenylmethyl)amino]-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepin-1-yl]acetamide (944 mg, 2.0 mmol) in ethanol (16 mL) were added Pd/C 10% (111 mg) and a solution of 4M HCl in dioxane (778 μl, 3.11 mmol). The resulting reaction mixture was hydrogenated at 3 bar for 6 h. The reaction mixture was quenched with sat. NaHCO3 (aq) and diluted with ethanol. After filtration through dicalite and thorough washing with ethyl acetate, the volatiles were removed in vacuo. A part of the crude product was purified with HPLC to afford the title compound (29 mg, 53%). Data (m/z)=378 (M+H)+.
