実験手順

To a solution of 2-propen-1-yl {3-[5-(2-chloro-4-pyrimidinyl)-2-(tetrahydro-2H-pyran-4-yl)-1,3-thiazol-4-yl]-2-fluorophenyl}carbamate (28 g, 59 mmol) in DCM (300 mL), HOAc (8.5 g, 141.6 mmol), Pd(PPh3)2Cl2 (0.827 g, 1.18 mmol) were added. Then tri-n-butyl tin hydride (27 g, 88.5 mmol) was added dropwise to the mixture at 0° C. The mixture was stirred at rt for 30 min. The reaction was quenched by added the saturated NaHCO3 (200 mL) slowly. The two layers were separated. The aqueous layer was extracted with DCM (300 mL×2). The combined organic layers were washed with water and brine successively, dried over Na2SO4, filtered and concentrated under reduced pressure to give the crude product, which was washed with petroleum ether (200 mL) to afford the title compound, which was used to the next step directly. (22.5 g, 97.8% yield). 1H NMR (400 MHz, CDCl3) δ ppm 8.35 (d, J=5.3 Hz, 1H), 7.01-7.08 (m, 1H), 6.98 (d, J=5.3 Hz, 1H), 6.85-6.92 (m, 1H), 6.79-6.85 (m, 1H), 4.05-4.12 (m, 2H), 3.79-3.86 (br, 2H), 3.51-3.59 (m, 2H), 3.23-3.34 (m, 1H), 2.07-2.15 (m, 2H), 1.89-2.01 (m, 2H).
