실험 절차

A solution of N-(2-(1,3-dioxolan-2-yl)-2,2-diphenylethyl)-3-fluoro-4-(2-(4-methylpyridin-2-ylamino)thiazol-5-ylthio)picolinamide (0.248 g, 0.4040 mmol, described in Example 50) in acetone (10 mL), water (5 mL), THF (5 mL) and conc. HCl (1 mL) was heated at gentle reflux for 10 hours. The reaction was then neutralized with aq. sat. sodium bicarbonate and the volatiles were evaporated. The solid was collected by filtration and vacuum dried to give the crude title material (0.240 g, 100%). 1H NMR (400 MHz, DMSO-d6) δ ppm: 2.30 (3H, s), 4.27 (2H, d, J=6.32 Hz), 6.83 (1H, d, J=4.55 Hz), 6.89 (1H, s), 7.03 (1H, t, J=5.31 Hz) 7.22 (4H, d, J=7.07 Hz) 7.31-7.37 (2H, m), 7.40 (4H, t, J=7.33 Hz) 7.77 (1H, s), 8.15 (1H, d, J=5.05 Hz), 8.19 (1H, d, J=5.05 Hz), 8.28 (1H, t, J=6.19 Hz). 9.99 (1H, s) 11.82 (1H, s).
