Reaction Steps

A solution of 2-Methoxy-4-[4-(4-methyl-piperazin-1-yl)-piperidin-1-yl]-phenylamine (0.18 g, 0.00059 mol) with 2-methanesulfinyl-7-(2-methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazine (85 mg, 0.30 mol) and N,N-diisopropylethylamine (0.057 g, 0.44 mmol) in 2-methoxyethanol (1.0 mL, 0.013 mol) in a microwave vessel was microwaved on 300 watts, 180° C. for 30 minutes. Repeated microwave for 30 minutes more to get to completion. Filtered through 0.45μ filter and purified by reverse phase HPLC. Concentrated and dissolved in DCM/MeOH and free-based with solid MP-carbonate.
