Conditions

Temperature: 150 °C

Procedure

Methyl 4-amino-3-(difluoromethoxy)benzoate (70 mg), 2,5-dichloro-N-methylpyrimidin-4-amine, 0.1 mL of 4N HCl/dioxane and 1 mL of n-butanol were placed in a microwave vial. The reaction was heated for 30 minutes at 150° C. and monitored by LCMS. The mixture was concentrated and purified by silica gel chromatography to give 100 mg of pure methyl 4-(5-chloro-4-(methylamino)pyrimidin-2-ylamino)-3-(difluoromethoxy)benzoate.
