Reaction Steps

7.1 ml of 2-bromoethanol in 50 ml of dichloromethane are added to a solution of 8.72 ml of chlorosulphonyl isocyanate in 40 ml of dichloromethane. The resulting solution is then added, at 0° C., to a solution of 11.23 ml of indoline and 15.46 ml of triethylamine in 200 ml of dichloromethane. After stirring for 24 hours at ambient temperature, 10N hydrochloric acid is added. The organic phase is then washed with hydrochloric acid and then with water, and is dried, filtered and concentrated, allowing the expected product to be obtained.
