To a stirred solution of 3-Amino-4-hydroxy benzoic acid (0.136, 0.00089 mols) and pyridine (0.211 g, 0.00267 mols) in 13 ml dry THF is added 4-trifluoromethoxybenzoyl chloride (0.2 g, 0.00089 mols) and the solution is stirred under nitrogen atmosphere at RT for 10 hrs and then refluxed for 3 hrs. The reaction mixture is rotary evaporated and the residue is slurried in water and filtered to get the amide (0.175 g) which is taken for the next step without further purification.
