Reaction Steps

A solution of 2-methoxy-4-[4-(1-methyl-piperidin-4-yl)-piperazin-1-yl]-phenylamine (140 mg, 0.45 mmol) and 2-methanesulfinyl-7-(2-methoxy-phenyl)-pyrrolo[2,1-f][1,2,4]triazine (65 mg, 0.23 mmol) in 2-methoxyethanol (0.50 mL) was treated with N,N-diisopropylethylamine (59 uL, 0.34 mmol). The reaction was heated under microwave conditions at 300 watts at 180° C. for 90 minutes. The mixture was diluted with methanol (10 mL), filtered and concentrated. The residue was purified by preparative RP-HPLC to give 65 mg of an amber amorphous powder.
