Reaction Conditions

Temperature130 °C

Reaction Steps

Two hundred milliliters of n-butanol was added to 3.0 g (0.02 mole) of 2-chloro-4-methylaminopyrimidine and 8.4 g (0.05 mole) of 4-phenylpiperidine, and the mixture was heated at 130° C. for 1 hour. The reaction mixture was concentrated under reduced pressure, and extracted with dichloromethane. The dichloromethane layer was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give 4.0 g (yield 71%) of the desired compound as an oil.
