Reaction Steps

Methyl 13-cyclohexyl-6-[methyl(3,11,11-trimethyl-7,7-dioxido-9-oxo-10-oxa-7-thia-3,8-diazadodec-1-yl)amino]-6,7-dihydro-5H-indolo[2,1-a][2]benzazepine-10-carboxylate was dissolved in DCM/TFA 3:1 (0.03M) and the mixture was left standing at RT. After 45 min all volatiles were evaporated in vacuo. The residue was dissolved in MeOH (0.07M) and 1M aqueous KOH solution (9 eq.) was added. The mixture was stirred at 65° C. for 4h. After cooling to 0° C. the pH of the solution was adjusted with 1 M aqueous HCl to pH 6. The resulting suspension was extracted with EtOAc. The combined organic phases were washed with brine and dried over Na2SO4. All volatiles were evaporated in vacuo. The residual material was used without further purification in the next reaction. (ES+) m/z 567 (M+H)+.
