1.84 g (10.0 mmol) 3-cyano-5-fluoro-benzoic acid chloride, 1.49 g (10.0 mmol) 4-methyl-3H-benzoxazol-2-one and 5.33 g (40.0 mmol) aluminium trichloride were heated to 125° C. for 1.5 h with stirring. Then the mixture was mixed with ice water. The precipitate formed was suction filtered, washed with water and dried i. vac.
