실험 절차

To a stirred suspension of the hydrochloride salt of 4-chloro-6-(5-chloro-2-methyl-phenyl)-pyrimidin-2-yl-amine (0.01 g, 0.0344 mmol) in ethanol (5 ml) was added a solution of hydrogen chloride in dioxane (4.0 M, 0.01 ml) followed by p-tolylamine (0.074 g, 0.068 mmol). The mixture was heated under reflux for 75 minutes. After evaporation of volatiles under reduced pressure, the residue was treated 1.0 M hydrochloric acid (10 ml) and stirred for 30 minutes. After filtration the solid was dissolved in methanol (5 ml) and treated with a solution of sodium carbonate in water (1.0 M, 1.0 ml). After stirring for 30 minutes volatiles were evaporated under reduced pressure. The residue was treated with water (10 ml) and stirred for 15 minutes. Filtration provided the title compound (0.011 g, 98% yield) as a white powder. 1H NMR (DMSO-d6) δ 2.27 (s, 3H, CH3), 2.34 (s, 3H, CH3), 6.07 (s, 1H, Ar), 6.33 (s, 2H, NH2), 7.10 (d, 2H, J=8.3 Hz, Ar), 7.30 (d, 1H, J=8.2 Hz, Ar), 7.35-7.40 (m, 2H, Ar), 7.61 (d, 1H, J=8.4 Hz, Ar), 9.09 (s, 1H, NH).
