Procedure

1.6 eq of 1-ethyl-(3-dimethylaminopropyl)carbodiimide HCl salt was added to a mixture of 2.7 eq of DMAP, 1.6 eq of methyl(aminosulfonyl)acetate and the hydrochloride salt of 14-cyclohexyl-3-methoxy-6-methyl-5,6,7,8-tetrahydroindolo[2,1-a][2,5]-benzodiazocine-11-carboxylic acid (from Example 4) in DCM (0.02 M). The reaction was stirred at RT overnight before being partitioned between aqueous HCl (1 N) and EtOAc. The organics were washed with saturated aqueous NaHCO3, water and brine before being dried over Na2SO4, filtered and concentrated in vacuo. The crude was then purified by RP-HPLC (stationary phase: column Waters XTERRA prep. C18, 5 um, 30×50 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 (18%).
