To a solution of methyl 14-cyclohexyl-6-(N,N-dimethylglycyl)-3-fluoro-5,6,7,8-tetrahydroindolo[2,1-a][2,5]benzodiazocine-11-carboxylate from (Step 6) in DCM (0.15 M) was added dropwise to a solution of BBr3 in DCM (1 M, 5 eq.). The solution was stirred at RT for 1 h. Some drops of saturated aqueous NaHCO3 were added before volatiles were removed in vacuo. The crude was then purified by automated RP-MS-HPLC (stationary phase: column Waters XTERRA prep. C18, 5 μm, 19×100 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 as a white powder (28%).
