反応手順
A solution of 8.2 g (39.4 mmol) of 2,3,4,5-tetrafluoro-6-methylbenzoic acid, 6.0 g (47.2 mmol) of oxalyl chloride, and 100 ml of dichloromethane was treated with three drops of DMF. The solution was stirred for three hours, then concentrated to give 8.8 g of the title compound as a yellow liquid. The product was used as is in the next step.
