Reaction Steps

Methyl 3-chloro-14-cyclohexyl-6-[2-(dimethylamino)ethyl]-5,6,7,8-tetrahydroindolo[2,1-a][2,5]benzodiazocine-11-carboxylate (from Step 7) was dissolved in a solution THF: MeOH (1:1) (0.02 M) and to that solution 7 eq of an aqueous solution of NaOH (1N) were added. The solution was stirred at 60° C. for 3 h. The solvent was evaporated in vacuo. The crude was then purified by automated RP-MS-HPLC (stationary phase: column Waters XTERRA prep. C18, 5 um, 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 (21%).
