実験手順

A mixture of N4,N4-dimethyl-N6-(4-methylphenyl)-2,4,6-pyrimidinetriamine (122 mg, 0.50 mmol), phenylacetyl chloride (84 mg, 0.55 mmol), and triethylamine (100 mg, 1.00 mmol) in CH2Cl2 was stirred at room temperature for 16 h. The crude product was concentrated in vacuo and treated with saturated NaHCO3 (50 mL) and extracted with CH2Cl2 (3×50 mL). The organic layer was washed with brine (2×100 mL), dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by preparative TLC using hexane/EtOAc (1:3), giving the desired product (60 mg, 33%).
