実験手順

A mixture of N-(3-dimethylamino-phenyl)-N′-methyl-pyrimidine-4,6-diamine (243.3 mg, 1 mmol), 2,6-dichlorophenyl isocyanate (188 mg, 1 mmol) in dry dimethylformamide (2.5 mL) is shaken for 14 h at 90° C. Two additional portions (188 mg, 1 mmol each) of 2,6-dichlorophenyl isocyanate are added after 14 h and 26 h. After 38 h the reaction mixture is evaporated in vacuo and the residue is distributed between ethyl acetate and half-saturated K2CO3 solution. The organic layer is dried over Na2SO4, evaporated, and the residue purified by flash chromatography (hexane/ethyl acetate). The combined pure fractions are evaporated, the residue triturated with CH2Cl2 and the solid filtered off and dried in vacuo to afford the title compound.
