Procedure

(3-{2-[4-(2-Pyrrolidin-1-yl-ethoxy)-phenylamino]-[1,2,4]triazolo[1,5-a]pyridin-5-yl}-phenyl)-carbamic acid tert-butyl ester (1.39 g, 2.71 mmol) was dissolved in dichloromethane (10 ml). Trifluoroacetic acid (10 ml) was added and the reaction mixture stirred for 2 hours. Neutralisation was performed by adding saturated aqueous sodium hydrogencarbonate. The aqueous phase was extracted twice with dichloromethane, and the combined organics washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the desired compound. Yield 830 mg, 74%. 50 mg was purified by preparatory LCMS.
