Sodium Fluoride → HCID 54234919, compound

Participants

Reaction Steps

15 g (0.1 mole) of 2-(N-acetylamino)-phenol in 100 ml of dry acetonitrile and 9 g (0.214 mole) of dry sodium fluoride were heated to 75°-80°C while stirring and 15 g (0.11 mole) of perfluoroazapropene were slowly passed into this suspension. After completion of the reaction, the mixture was filtered, the solvent was concentrated and the residue was recrystallized from chloroform. 15 g of 2-trifluoromethylimino-3-acetyl-benzoxazoline were obtained as pale yellow prisms of melting point 140°-143°C. The yield of pure material was 67% of theory.
