Procedure

To a mixed solution of the compound (200 mg, 0.49 mmol) obtained in step 4 in THF (2 mL) and methanol (2 mL) was added 1N aqueous sodium hydroxide solution (0.972 ml, 0.97 mmol) at room temperature, and the mixture was stirred at 60° C. for 3 hr. The reaction mixture was cooled to room temperature, and 1N hydrochloric acid was added until the mixture became pH 2-3. The mixture was extracted with ethyl acetate, the organic layer was dried, and the solvent was evaporated under reduced pressure to give (E)-3-(2-(1-(tert-butyl)-5-(4-methoxyphenyl)-1H-pyrazol-4-yl)thiazol-4-yl)acrylic acid (180.7 mg, 0.471 mmol, 97%) as a white powder.
