実験手順: Add potassium hydroxide (899 mg, 16.64 mmol) in one portion to a solution of 3-tert-butoxycarbonyl-7-chloro-6-dimethylcarbamoylthio-2,3,4,5-tetrahydro-1H-benzo[d]azepine (200 mg, 0.52 mmol) in methanol (10 mL). Heat the reaction to 50° C. under nitrogen for 24 h, then cool to room temperature and add 1-(3-chloro-propyl)-1,3-dihydro-indol-2-one (217 mg, 1.04 mmol). Stir the reaction at room temperature for 4 days. Remove solvents in vacuo, add dichloromethane (20 mL) and water (20 mL). Remove the organic layer and dry using an ISCO® phase separator then concentrate in vacuo to give 3-tert-butoxycarbonyl-7-chloro-6-[3-(2-oxo-2,3-dihydro-indol-1-yl)-propylthio]-2,3,4,5-tetrahydro-1H-benzo[d]azepine as orange powder. MS (ES+) m/z: 509 (M+Na)+. Heat the reaction to 50° C. under nitrogen for 24 h the reaction at room temperature for 4 days Remove the organic layer dry then concentrate in vacuo
