Hydrochloric Acid → N-[5-Methyl-2-(2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-methanesulfonamide

Participants

Reaction Steps

To a mixture of 5-Methyl-2-(2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenylamine (480 mg, 1.8 mmol) in dry pyridine (4 mL, 50 mmol) was added at 0° C. methanesulfonyl chloride (160 uL, 2.1 mmol). The mixture was stirred for 2 h and was thrown to 3N HCl. The mixture was extracted from EtOAc. Combined organic was washed with brine and was dried. After solvent evaporation, the product, N-[5-Methyl-2-(2-methylsulfanyl-pyrrolo[2,1-f][1,2,4]triazin-7-yl)-phenyl]-methanesulfonamide, was obtained as a yellow solid (591 mg, 96%). The solid was used directly for the next step.
