실험 절차
A mixture of 6-chloro-N4-(4-methylphenyl)-2,4-pyrimidinediamine (1.5 g, 6.4 mmol) and N,N-dimethylamine hydrochloride (0.56 g, 7 mmol) and triethylamine (1.4 g, 14 mmol) in DMF (2 mL), was heated at 170° C. for 16 h. The product was filtered out and the organic layer was treated with saturated NaHCO3 (50 mL) and extracted with EtOAC (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 chromatography on silica using hexane/EtOAc (1:3), giving the desired product (0.6 g, 40%).
