Procedure

4-Hydroxy-4-(4-{7-[2-(methanesulfonyl-methyl-amino)-phenyl]-pyrrolo[2,1-f][1,2,4]triazin-2-ylamino}-3-methoxy-phenyl)-piperidine-1-carboxylic acid tert-butyl ester (41 mg) was dissolved in dichloromethane (1 ml), and trifluoroacetic acid (1 ml) was added. The solution was stirred 2 hours at room temperature, and then concentrated. Purification on Gilson reverse phase chromatograph (15% to 45% acetonitrile/water gradient) and lyophilization afforded N-(2-{2-[2-methoxy-4-(1,2,3,6-tetrahydro-pyridin-4-yl)-phenylamino]-pyrrolo[2,1-f][1,2,4]triazin-7-yl}-phenyl)-N-methyl-methanesulfonamide, compound with trifluoroacetic acid as an orange solid, 16 mg. mp 204-205° C. LCMS (E/I+) 505 (M+H).
