Reaction Steps

To a stirred solution of ethyl trifluoroacetate (500 mg, 3.52 mmol) in tert-butyl methyl ether (4 ml) was added sodium methoxide (28 wt.% solution in methanol; 0.9 ml, 4.0 mmol) over 2 min. A solution of 1-[3-methyl-4-(1,3-thiazol-4-yl)phenyl]-1-ethanone from step 4 (714 mg, 3.33 mmol) in t-butylmethylether (6 ml) was added dropwise over 5 minutes, and the mixture was stirred for 20 hours. 2N HCl (10 ml) was added, and the whole was extracted with ethyl acetate. The organic layer was washed with brine, dried over MgSO4, and concentrated in vacuo, and the residue was used for next reaction without further purification. (1.05 g, 99% yield).
