HCID 58386747HCID 58386747, compound

Procedure

2.00 g (11.8 mmol) 4,5-difluoro-1,3-dihydro-indol-2-one I were stirred in 6.62 mL (55.0 mmol) acetic anhydride for 2 h at 150° C. The reaction mixture was added to ice water, the precipitated solid was suction filtered and washed with water. The product was recrystallised from a mixture of water and ethanol, suction filtered and dried.
