Reaction Steps

To a solution of methyl 14-cyclohexyl-5-[2-(dimethylamino)ethyl]-6-oxo-5,6,7,8-tetrahydroindolo[1,2-e][1,5]benzodiazocine-11-carboxylate in DCM (0.1M) 7 eq BBr3 (1M solution in DCM) were added. The solution stirred at RT for 20 mins. The volatiles were evaporated in vacuo. The crude was then purified by prep RP-HPLC (stationary phase: column Waters XTERRA prep. C18, 5 um, 19×150 mm. Mobile phase: MeCN/H2O buffered with 0.1% TFA). Fractions containing the pure compound were combined and freeze dried to afford the title compound (40% over two steps).
