Procedure

1.45 g (8.21 mmol) 3,5-difluorobenzoic acid chloride, 1.22 g (8.21 mmol) 4-methyl-3H-benzoxazol-2-one and 4.40 g (33.0 mmol) aluminium trichloride were heated to 125° C. for 1.5 h with stirring. The mixture was mixed with ice water and the product precipitated as a solid was suction filtered and washed with water. After trituration of the precipitate with MeOH it was suction filtered, washed with MeOH and dried i. vac.
