Procedure

A solution of (3-amino-5-chloro-pyridin-2-yl)-pyridin-3-yl-methanone (26 mg, 0.11 mmol), 4-chloro-3-trifluoromethyl-benzenesulfonyl chloride (28 mg, 0.10 mmol), DMAP (7.3 mg, 0.06 mmol) in anhydrous pyridine (0.5 mL) was heated at 60° C. for 2 days. The reaction mixture was separated by preparative HPLC and pure product fractions were lyophilized to provide pure product as a solid. 1H NMR (400 MHz, CDCl3) δ 11.03 (s, 1H), 9.15 (s, 1H), 8.81-8.80 (m, 1H), 8.37 (d, J=2.0 Hz, 1H), 8.29-8.26 (m, 1H), 8.20-8.18 (m, 2H), 7.98 (dd, J=8.4, 2.8 Hz, 1H), 7.63 (d, J=8.4 Hz, 1H), 7.51-7.48 (m, 1H). Mass spectrum m/z: 476.0 (M+H).
