Reaction Steps

Methyl 14-cyclohexyl-3-fluoro-6-(1H-imidazol-1-ylacetyl)-5,6,7,8-tetrahydroindolo[2,1-a][2,5]benzodiazocine-11-carboxylate was dissolved in a solution of dioxane: H2O (1:1) (0.1 M) and to that solution aqueous KOH (3 eq, 5 N) 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 SYMMETRY prep. C18, 7 μm, 19×300 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 (41%).
