Reaction Steps
To a 30 mL microwave vial was added 0.98 g of 2,5-dichloro-N-methylpyrimidin-4-amine, 0.78 g of methyl 5-amino-1-methyl-1H-pyrazole-3-carboxylate, 10 mL of 1-butanol and 0.13 mL of 4M hydrogen chloride in dioxane. The vial was capped and the reaction was heated in a microwave for 30 minutes at 130° C. As the reaction cooled, a precipitate fell out. Filter the precipitate and rinse with a small amount of n-butanol. Drying the cake yielded 0.964 g of methyl 5-(5-chloro-4-(methylamino)pyrimidin-2-ylamino)-1-methyl-1H-pyrazole-3-carboxylate which was used without further purification.
