Reaction Steps

Prepared from 0.60 g (2.17 mmol) of 4-chloro-3-trifluoromethyl-benzenesulfonyl chloride and 0.30 g (1.97 mmol) of 3-amino-pyridine-2-carboxylic acid methyl ester in 3 mL pyridine using procedure x. The solvent was switched to THF, followed by the addition of 1 M aqueous LiOH and the mixture stirred for 1 h. The pH of the mixture was adjusted to neutral and the product was extracted with ethyl acetate. LC-MSD, m/z for C13H8ClF3N2O4S [M+H]+=380.9, 383.0; HPLC retention time: 1.8 min.
