Procedure

To a solution of methyl (7S)-7-[(1-benzylpyrrolidin-2-yl)methoxy]-14-cyclohexyl-7,8-dihydro-6H-indolo[1,2-e][1,5]benzoxazocine-11-carboxylate (0.07 M) in EtOAc, was added an excess of AcOH (>50 eq) and Pd(OH)2/C. The atmosphere in the reaction flask was charged with H2 and the reaction stirred vigorously under a H2 atmosphere (balloon) at RT for 2 d. The mixture was filtered and the filtrate concentrated in vacuo. The crude was purified by FC (gradient from EtOAc/PE 6:4+1% NEt3 to EtOAc/PE 8:2+1% NEt3+5% MeOH) to afford the product (50%). (ES+) m/z 489 (M+H)+.
