Procedure

A solution of tert-butyl 4-(2-(2-(3-fluoro-4-(2-(piperidin-1-yl)ethoxy)phenyl)-3-phenylfuro[2,3-b]pyridin-4-ylamino)ethyl)piperazine-1-carboxylate (0.058 g, 0.090 mmol) in dichloromethane (2.0 mL) was cooled to 0° C. Trifluoroacetic acid (1.0 mL) was added and the solution stirred under a nitrogen atmosphere at 0° C. for 2 h. The reaction mixture was concentrated and the residue was partitioned between ethyl acetate and saturated aqueous sodium bicarbonate solution. The organic phase was separated and washed with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, filtered and concentrated to afford a yellow oil. This oil was purified via preparative thin layer chromatography (eluting with 90:10:1, dichloromethane/methanol/ammonium hydroxide) to afford 2-(3-fluoro-4-(2-(piperidin-1-yl)ethoxy)phenyl)-3-phenyl-N-(2-(piperazin-1-yl)ethyl)furo[2,3-b]pyridin-4-amine 10 g as a white solid. MS (MH+) 544.3; Calculated 543 for C32H38FN5O2.
