実験手順

Methyl 10-((aminosulfonyl)carbamoyl)-13-cyclohexyl-3-methoxy-7H-indolo[2,1-a][2]benzazepine-6-carboxylate (725 mg, 1.39 mmol) was dissolved into MeOH//THF (1:1, 16 mL) and treated with 1M aqueous NaOH (3 mL). The reaction mixture was stirred and heated at 60° C. for 0.5 h and cooled to rt. The reaction solution was diluted with MeOH/H2O (2:1, 15 mL), neutralized with 1M aqueous HCl (3 mL) and concentrated to remove organic solvents. The resultant solids were collected by filtration, washed with H2O and dried under vacuum to yield 10-((aminosulfonyl)carbamoyl)-13-cyclohexyl-3-methoxy-7H-indolo[2,1-a][2]benzazepine-6-carboxylic acid (650 g, 1.3 mmol, 92%) as a bright yellow solid which was used without further purification. 1H NMR (300 MHz, CDCl3) δ 1.16-2.22 (m, 10H), 2.82-2.96 (m, 1H), 3.94 (s, 3H), 4.07-4.29 (m, 1H), 5.57-5.80 (m, 1H), 7.14-7.23 (m, 2H), 7.55-7.63 (m, 2H), 7.88-7.94 (m 2H), 8.18 (s, 1H). LCMS: m/e 510 (M+H)+, ret time 2.85 min, column B, 4 minute gradient.
