Reaction Steps

To a solution of methyl 14-cyclohexyl-5,6,7,8-tetrahydroindolo[1,2-e][1,5]benzodiazocine-11-carboxylate in DCE (0.05 M) 1 eq of formaldehyde (37 wt. % sol. in H2O) and 2 eq of NaBH(OAc)3 were added and the solution stirred at RT for 1 h. The reaction mixture was diluted with EtOAc. The organic phase was washed with NaHCO3 (s.s.) and brine. The organic phase was dried over Na2SO4 filtered and concentrated in vacuo. The title compound was used directly in the next step; MS (ES+) m/z 403 (M+H)+.
