1-Methoxy-2-propanol → N-[2-(2-{4-[4-((R)-2-Hydroxy-propyl)-piperazin-1-yl]-phenylamino}-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-N-methyl-methanesulfonamide

Reaction Steps

(R)-1-[4-(4-Amino-phenyl)-piperazin-1-yl]-propan-2-ol (129.1 mg, 0.5488 mmol), N-[2-(2-Methanesulfinyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-N-methyl-methanesulfonamide (100.0 mg, 0.2744 mmol) and N,N-Diisopropylethylamine (0.1434 mL, 0.8232 mmol) were dissolved in 1-Methoxy-2-propanol (1.00 mL, 10.2 mmol). The reaction was irradiated at 300 watts, 200° C. for 20 minutes or until HPLC showed consumption of starting material. The mixture was then reduced under nitrogen and the product was isolated and purified by Gilson prep HPLC to afford 61.36 mg of N-[2-(2-{4-[4-((R)-2-Hydroxy-propyl)-piperazin-1-yl]-phenylamino}-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-N-methyl-methanesulfonamide as a lyophilized powder.
