Procedure

Cyclopropanecarboxylic acid [5-(4-amino-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-amide (0.05, 0.17 mmol) was suspended in dichloromethane (2 mL). Pyridine (0.027 mL, 0.34 mmol) and ethanesulfonyl chloride (0.019 mL, 0.204 mmol) were added and the mixture was stirred for 4 hours. A further equivalent of pyridine and ethanesulfonyl chloride were added and the mixture was stirred overnight. The volatiles were removed in vacuo and the crude product was purified by preparatory HPLC. LCMS method: 2, RT: 3.11 min, MI: 386 [M+1]. NMR (1H, DMSO, 300 MHz): 0.82 (d, 4H), 1.24 (t, 3H), 2.01 (brs, 1H), 3.20 (q, 2H), 7.27 (dd, 1H), 7.36 (d, 2H), 7.68 (m, 2H), 8.02 (d, 2H), 9.98 (brs, 1H), 11.15 (s, 1H).
