実験手順

To a stirred solution of lithium 2-(2-(2-(2-((4-(4-(tert-butoxycarbonyl)piperazin-1-yl)-2-methoxyphenyl)amino)-5-(trifluoromethyl)pyrimidin-4-yl)ethyl)phenyl)acetate (I7) (0.352 g, 0.672 mmol), 1-hydroxybenzotriazole (0.093 g, 0.686 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide)hydrochloride (0.121 g, 0.629 mmol) in dry tetrahydrofuran (16 mL) and dimethylformamide (7 mL) was added N,N-diisopropylethylamine (0.498 mL, 2.86 mmol) under a nitrogen atmosphere. The reaction mixture was stirred for 10 minutes at room temperature then ammonium carbonate (0.263 g, 2.859 mmol) was added and the resulting suspension was stirred at room temperature for 18 hours. The reaction volatiles were evaporated in vacuo and the resulting residue was diluted with ethyl acetate (15 mL) and water (10 mL). The layers were separated and the aqueous layer was extracted with ethyl acetate (2×15 mL). The combined organic extracts were washed with water, brine, dried (magnesium sulfate) and concentrated in vacuo to give a yellow foam which was purified by flash column chromatography on silica gel (55-85% ethyl acetate/petroleum ether) to give the title compound (I8) (0.276 g, 87%) as a yellow foam; 1H NMR (300 MHz, CDCl3) δ 1.48 (d, 9H, J=1.1 Hz), 3.09 (d, 8H, J=3.9 Hz), 3.58 (brs, 4H), 3.66 (s, 2H), 3.88 (d, 3H, J=1.0 Hz), 5.48 (brs, 1H), 5.78 (brs, 1H), 6.54 (d, 1H, J=1.3 Hz), 6.57 (s, 1H), 7.23-7.25 (brs, 4H), 7.72 (s, 1H), 8.13 (d, 1H, J=8.6 Hz) and 8.48 (s, 1H). LCMS Method B: rt 8.52 min; m/z 615.4 [M+H]+.
