Procedure

A solution of (3-amino-5-chloro-pyridin-2-yl)-phenyl-methanone (40 mg, 0.17 mmol), 4-chloro-3-trifluoromethyl-benzenesulfonyl chloride (72 mg, 0.26 mmol), and DMAP (11 mg, 0.09 mmol) in anhydrous pyridine (0.5 mL) was heated at 60° C. for 4 days. The product was separated by preparative HPLC and pure product fractions were lyophilized to provide pure product as a solid.
