Procedure
({4-[2-(Cyclopropanecarbonyl-amino)-[1,2,4]triazolo[1,5-a]pyridin-5-yl]-phenylcarbamoyl}-methyl)-carbamic acid tert-butyl ester (0.08 g, 0.17 mmol) was dissolved in dichloromethane (3 ml), microporous p-toluenesulfonic acid (0.16 g, 0.51 mmol) was added and the mixture was shaken overnight. The resin was washed several times with methanol, and then the product was cleaved from the resin using a 2M ammonia/methanol solution. This solution was concentrated in vacuo to give clean product. LCMS method: 2, RT: 1.86 min, MI: 351 [M+1]. NMR (1H, DMSO, 300 MHz): 11.04 (brs, 1H), 8.02 (d, 2H), 7.82 (d, 2H), 7.66 (m, 2H), 7.28 (dd, 1H), 3.34 (brs, 2H), 2.03 (brs, 1H), 0.82 (d, 4H).
