Procedure

Oxalyl chloride (0.64 g) in dry ether (7 ml) was added dropwise with stirring to 2-trifluoromethyl-4-(2',2'-dimethylpropionamido)-benzoic acid (0.926 g) in dry ether (40 ml) at room temperature. A drop of DMF was added during the addition. After two hours further oxalyl chloride (0.257 g) was added and the reaction stirred for a further two hours. The organic solution was then decanted from a precipitate, and evaporated to yield 2-trifluoromethyl-4-(2',2'-dimethylpropionamido)-benzoyl chloride as a liquid (1.136 g), which was used without purification.
