After 2 hours 6-amino-1-cyclopropyl-3,3-dimethyl-1,3-dihydro-indol-2-one (example 14c, 150 mg, 694 μmol) and triethyl amine (140 mg, 193 μl, 1.39 mmol) were added at 0° C. The reaction mixture was warmed to room temperature, kept at this temperature for 16 hours, then diluted with dichloromethane, water and 1 M aqueous sodium carbonate solution. The aqueous phase was extracted with dichloromethane. The combined organic layers were washed with 1 M aqueous sodium carbonate solution, dried over sodium sulfate, the solvent was evaporated and the residue was purified by silica gel chromatography using dichloromethane/methanol as eluent. The title compound was obtained as light yellow oil (207 mg).
