Reaction Steps
A mixture of 2.4 g of 1-bromo-3,3,4,4,4-pentafluorobutan-2-one and 5 ml of DME was added to a mixture of 1.87 g of 2-amino-5-bromo-6-methylpyridine and 10 ml of DME, and the mixture was stirred at room temperature for 3 hours. The precipitated solid was filtered, and washed with 10 ml of DME to obtain 3.95 g of 6-bromo-5-methyl-2-pentafluoroethyl-2,3-dihydroimidazo[1,2-a]pyridin-2-ol hydrobromide.
