Reaction Steps

N—[(S)-5-(2-Benzyloxy-ethyl)-6-oxo-6,7-dihydro-5H-dibenzo[b,d]azepin-7-yl]-2-methyl-N′-(2,2,3,3,3-pentafluoro-propyl)-malonamide (113 mg, 0.19 mmol) were dissolved in methanol (20 ml) and treated with 37% aqueous HCl (0.1 ml) and palladium on carbon (10%, 6 mg) and stirred for 2 days under an atmosphere of hydrogen. After filtration and evaporation of the solvent, the title compound was obtained as white solid (94%). MS: m/e=450(M+H+).
