Procedure

To a solution of methyl 14-cyclohexyl-7-oxo-7,8-dihydro-6H-indolo[1,2-e][1,5]benzoxazocine-11-carboxylate (from Step 4) in 1,2-dichloroethane (0.08 M), were added 1.0 eq of N,N-dimethylethane-1,2-diamine and 1.5 eq acetic acid, followed by 1.5 eq. of solid sodium triacetoxyborohydride. NaOH (20 eq, 1 N) was added after 2 h, and after stirring for 5 min the mixture was taken into EtOAc and washed with water and brine. Drying over sodium sulfate and concentration in vacuo gave the crude product, which was used without further purification; MS (ES+) m/z 476 (M+H)+.
