실험 절차

A mixture of the amine from example 4 (500 mg, 1.3 mmol), potassium carbonate (480 mg, 3.5 mmol) and 4-chloropyrimidine (300 mg, 2.6 mmol) was stirred at 95° C. for 18 hours. The cooled reaction mixture was diluted with ethyl acetate and the solution was washed with brine (5×), then dried over magnesium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography on silica gel using dichloromethane:methanol (100:0 to 95:5) as eluant, and the product was triturated with diethyl ether to afford the title compound (80 mg).
