実験手順

To a stirred solution of 1-[2-fluoro-4-(1,3-thiazol-4-yl)phenyl]-1-ethanone (2.03 g, 9.18 mmol) in t-butylmethylether (60 ml) was added ethyl trifluoroacetate (1.56 g, 11.01 mmol), sodium methoxide (28 wt. % solution in methanol; 2.49 ml, 11.01 mmol) at 0° c, and the mixture was stirred for 3 hours. The mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over MgSO4, and concentrated in vacuo to give title compound (2.92 g, 99% yield). The compound was used for next reaction without purification.
