実験手順

2-[4-(Piperazin-1-yl)anilino]-4-(1-isopropyl-2-methyl-1H-imidazol-5-yl)pyrimidine (Example 20; 330 mg 0.88 mmol) was stirred in DCM (6 ml) at room temperature. Triethylamine was added (153 mg 1.51 mmol) followed by dropwise addition of acetoxyacetylchloride (143 mg 1.05 mmol). After stirring for 1.25 hours, DCM (10 ml) and brine (5 ml) were added. The reaction was stirred vigorously for 10 minutes then the organic layers were separated, dried and evaporated under reduced pressure to give the title compound as a yellow foam. Quantitative yield. The solid was triturated with ether and re-evaporated. NMR: 1.40 (d, 6H), 2.08 (s, 3H), 2.48 (s, 3H), 3.05 (b d, 4H), 3.54 (b d, 4H), 4.81 (s, 2H), 5.70 (septuplet, 1H), 6.92 (d, 2H), 6.95 (d, 1H), 7.40 (s, 1H), 7.48 (d, 2H), 8.31 (d, 1H), 9.18 (s, 1H); m/z 478.
