Reaction Steps
A solution of 5-bromo-2-(2,5-dimethyl-1H-pyrrol-1-yl)-N-(trans-4-methoxycyclohexyl)-6-methylpyrimidin-4-amine (1.07 g, 2.72 mmol) and hydroxylamine hydrochloride (945 mg, 13.6 mmol) in 10:1 ethanol:water (27.5 mL) was heated to reflux for 7 hours, then room temperature overnight. Another 0.5 eq of hydroxylamine hydrochloride was added and the solution was refluxed for another 4 hours, then cooled to room temperature and concentrated. The crude product was purified by flash chromatography eluting with chloroform/methanol (0.5-3%) to afford 5-bromo-N4-(trans-4-methoxycyclohexyl)-6-methylpyrimidine-2,4-diamine (767 mg, 89%).
