Procedure

{5-[3-(4-Methoxy-phenoxy)-phenyl]-[1,2,4]triazolo[1,5-a]pyridin-2-yl}-[4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-amine (2.90 g, 5.41 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 was extracted twice with dichloromethane, then the combined organics were washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the desired compound. Yield 2.01 g, 89%. 50 mg was purified by preparatory HPLC.
