Participants

Reaction Steps

To a solution of cyclopropanecarboxylic acid [5-(4-hydroxy-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-amide (WW-022) (0.05 g, 0.17 mmol) in acetonitrile (3 mL), potassium carbonate (0.047 g, 0.34 mmol) was added and the mixture was refluxed for 30 min. 3-Methoxybenzylbromide (0.047 mL, 0.34 mmol) was then added and the solution was refluxed overnight. The mixture was filtered and purified by preparatory HPLC. LCMS method: 1, RT: 5.16 min; MI: 415 [M+1]. NMR 1H (DMSO): 0.79-0.83 (m, 4H), 2.06 (brs, 1H), 3.76 (s, 3H), 5.08 (s, 2H), 6.88 (dd, 1H), 77.03-7.08 (m, 2H), 7.16 (d, 2H), 7.24 (dd, 1H), 7.31 (t, 1H), 7.60-7.67 (m, 2H), 8.00 (dd, 2H).
