Dichloromethane → N-(2-chloropyridin-4-yl)-4-(2-{[1-(methoxymethyl)propyl]amino}pyridin-4-yl)pyrimidin-2-amine

Participants

Reaction Steps

300 mg of N,4-bis(2-chloropyridin-4-yl)pyrimidin-2-amine (0.94 mmol), 486 mg of 1-methoxybutan-2-amine (4.71 mmol), were heated at 240° C. for 90 minutes under micro-waves irradiation in 0.6 ml of 1-Methyl-2-pyrrolidinone. After cooling, the reaction mixture was poured into 10 ml of dichloromethane, washed twice with 5 ml of water. After drying over magnesium sulfate, filtration and concentration in vacuo, the crude product was chromatographed on silica (ethyl acetate/heptane) to yield 0.72 g of N-(2-chloropyridin-4-yl)-4-(2-{[1-(methoxymethyl)propyl]amino}pyridin-4-yl)pyrimidin-2-amine (yield=19%).
