Reaction Steps

To a stirred solution of 4-Amino-3-hydroxy benzoic acid (0.490 g, 0.0032 mols) and pyridine (0.76 g, 0.0096 mols) in 50 ml dry THF is added 6-chloronicotinoyl chloride (0.56 g, 0.0032 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 (0.8 g) which is taken for the next step without further purification.
