実験手順

A mixture of [(6-chloro-2-methylpyrimidin-4-yl)-(2,4,6-trimethylpheny)-amino]-acetic acid ethyl ester (85 mg, 0.244 mmol) and N-butyl-ethylamine (0.17 ml, 1.1 mmol) in 4 ml DMSO was heated at 135° C. for 15 hours. An additional 1 ml of N-butyl-ethylamine was added and the reaction was heated at that temperature for an additional 15 hours (tic showed no starting material). The mixture was quenched with water and extracted with ethyl acetate. The organic layer was separated, dried and concentrated to give 123 mg of a light amber oil. The oil was purified through silica gel chromatotron using 5% ethyl acetate in hexane as eluent to give 92 mg (91%) of the title compound as a white glass. 1H NMR (CDCl3) δ 6.94 (s, 2H), 4.69 (s, 1H), 4.23 (s, 2H), 4.22 (q, 2H), 3.35 (q, 2H), 3.15 (t, 2H), 2.36 (s, 3H), 2.31 (s, 3H), 2.21 (s, 6H), 1.3–1.5 (m, 2H), 1.34 (t, 3H), 1.1–1.3 (m, 2H), 1.01 (t, 3H), 0.80 (t, 3H) ppm.
