Reaction Steps

Analogous to Example 1528d, 2-(3-Amino-phenyl)-piperazine-1,4-dicarboxylic acid di-tert-butyl ester (204 mg, 0.540 mmol) and Trifluoro-methanesulfonic acid 7-(6-methoxy-pyridin-3-yl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl ester (162 mg, 0.432 mmol) were reacted to afford [7-(6-Methoxy-pyridin-3-yl)-pyrrolo[2,1-f][1,2,4]triazin-2-yl]-(3-piperazin-2-yl-phenyl)-amine (75 mg, 33%) as the TFA salt.
