実験手順

To the solution of 2-propen-1-yl[3-[5-(2-chloro-4-pyrimidinyl)-2-(1-methylethyl)-1,3-thiazol-4-yl]-2-(methyloxy)phenyl]carbamate (12.1 g, 22.5 mmol) in DCM (200 mL), acetic acid (3.8 mL, 66.6 mmol), Pd(PPh3)2Cl2 (0.45 g, 0.56 mmol) were added. Then tri-n-butyl tin hydride (8.5 mL, 33 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 (200 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 (500 mL) to afford the title compound of Step G (10 g, 60.8% yield), which was used directly in the next step.
