実験手順

A suspension of 5-[4-chloro-6-(4-methoxy-phenylamino)-[1,3,5]triazin-2-ylamino]-3-methyl-imidazolidine-2,4-dione (Example 1.10, Part A) (50 mg, 0.14 mmol), p-methoxyaniline (25 mg, 0.21 mmol) and potassium carbonate (48 mg, 0.34 mmol) in anhydrous DMF (5 mL) was stirred under a nitrogen atmosphere for 18.5 h. The reaction mixture was diluted with water and the crude product was extracted with ethyl acetate. The organic layer was dried and evaporated, and the crude product was purified by column chromatography (silica; dichloromethane:ethyl acetate starting with a solvent ratio of 10:1 and increasing the polarity to dichloromethane:methanol, 10:1) to afford the product as a pale yellow solid (36 mg, 58%). δH (300 MHz, (CD3)2CO) 8.14 (br s, 2H, NH), 7.60 (br s, 4H, ArH (ortho to NH attach)), 7.43 (br s, 1H, NH), 6.91 (d, J 8.7 Hz, 1H, NH), 6.85 (d, J 9.0 Hz, 4H, ArH (ortho to O attach)), 5.91 (d, J 7.8 Hz, 1H, CH), 3.77 (s, 6H, OCH3), 2.86 (br s, 2.0H, NCH3), 2.73 (br s, 1.0H, NCH3). Mass spectrum (ESI) m/z 451 (37%, MH+).
