Versuchsvorschrift

Similarly, 4-({4-[1-(3-fluoro-benzyl)-1H-indazol-5ylamino]-pyrrolo[2,1-f][1,2,4]triazin-5-ylmethyl}-amino)-piperidin-1-carboxylic acid tert-butyl ester was convertet to 4-({4-[1-(3-fluoro-benzyl)-1H-indazol-5-ylamino]-pyrrolo[2,1-f][1,2,4]triazin-5-ylmethyl}-methylamino)-piperidin-1-carboxylic acid tert-butyl ester which was treated with TFA at 0° C. for 1 h to give the title compound as a solid (overall yield 37%). MS: 485 (M+H)+; HPLC Ret Time: 0.95 min (YMC 3.0×50 mm S7 C18 column, 2 min gradient, 5 ml/min).
