実験手順

A suspension of N-(2-{[(1,1-dimethylethyl)(dimethyl)silyl]oxy}ethyl)-2,3,4-trifluoro-N-methylbenzamide (300 mg, 0.86 mmol), 3-hydroxy-5-[(1S)-2-methoxy-(1-methylethyl)oxy]-N-(1-methyl-1H-pyrazol-3-yl)benzamide (278 mg, 0.91 mmol) and potassium carbonate (237 mg, 1.73 mmol) in DMA (20 mL) was heated to 140° C. for 1 hour. The reaction mixture was poured into water (100 mL) and extracted with ethyl acetate (3×50 mL). The combined organic phases were washed with brine (50 mL) and dried (MgSO4), filtered and evaporated to give an orange oil. This was purified via column chromatography on silica, eluting with 50-100% ethyl acetate in isohexane, to give the desired product as a colourless oil (322 mg). 1H NMR δ (CDCl3): 1.25 (d, 3H), 2.77 (s, 3H), 3.33 (s, 3H), 3.44 (dd, 1H), 3.50 (dd, 1H), 3.71 (s, 3H), 3.74 (t, 2H), 4.25 (t, 2H), 4.49-4.56 (m, 1H), 6.71 (d, 1H), 6.73 (t, 1H), 6.75 (dd, 1H), 7.04 (t, 1H), 7.20-7.20 (m, 1H), 7.22 (d, 1H), 7.47 (dd, 1H), 8.68 (s, 1H); m/z 499 (M+H)+
