Procedure

To a solution of methyl({[(14-cyclohexyl-3-methoxy-6-methyl-5,6,7,8-tetrahydroindolo[2,1-a][2,5]benzodiazocin-11-yl)carbonyl]amino}sulfonyl)acetate (from example 5) in dioxane (0.04 M) was added an equal volume of water and 4 eq of NaOH (1 N aqueous solution). The reaction was stirred vigorously at RT for 1 h. The reaction was acidified with aqueous HCl (1 N) and reduced in vacuo to remove dioxane. The resultant aqueous slurry was diluted with MeCN and water and freeze dried to leave a white powder. 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 (72%).
