実験手順

To a solution of 2-propen-1-yl {3-[5-(2-chloro-4-pyrimidinyl)-2-(1,1-dimethylethyl)-1,3-thiazol-4-yl]-4-fluorophenyl}carbamate (11 g, 24.6 mmol) in DCM (200 mL), HOAc (3.6 g, 59.2 mmol), Pd(PPh3)2Cl2 (345 mg, 0.5 mmol) were added. Then tri-n-butyl tin hydride (8.6 g, 29.6 mmol) was added dropwise to the mixture at 0° C. The mixture was stirred at rt for 30 min. The reaction was quenched by adding saturated NaHCO3 (100 mL) slowly. The two layers were separated. The aqueous layer was extracted with DCM (100 mL×2). The combined organic layers were washed with water and brine successively, dried over Na2SO4, filtered and concentrated under reduced pressure and washed with petroleum ether (200 mL) to afford the crude product, 3-[5-(2-chloro-4-pyrimidinyl)-2-(1,1-dimethylethyl)-1,3-thiazol-4-yl]-4-fluoroaniline (7.62 g, 85.3% yield), 7.4 g of which was used directly in the next step.
