Reaction Conditions

Reaction Steps

A mixture of cyclohexylamine (1.78 g, 18 mmol) and 6-chloro-N,2-dicyclopropyl-5-methyl-4-pyrimidinamine 33 (0.70 g, 3 mmol) in 1-methoxy-2-propanol (2 ml) is stirred at 125° C. for 120 hours. After cooling, the brown solution is diluted with dichloromethane, washed two times with a saturated sodium bicarbonate solution. The combined organic layers are dried over magnesium sulfate and concentrated under high vacuum to afford a brown oil. The crude oil is purified by column chromatography (dichloromethane/methanol: 97.3/2.7) to give pure N4-cyclohexyl-N6,2-dicyclopropyl-5-methyl-4,6-pyrimidinediamine 141 (0.150 g, 17%).
