Participants

Reaction Steps

To a mixture of THF (2 mL), methanol (2 mL), and 2N sodium hydroxide aqueous solution of 3-(2,6-difluoro-4-{4-[2-fluoro-3-(1-methyloxyhexyl)phenyl]thiazol-2-ylcarbamoyl}phenyl}-2-methylacrylic acid ethyl ester (500 mg) was stirred at room temperature for 3 h. The reaction mixture was acidified with hydrochloric acid, and extracted with ethyl acetate. The organic layer was washed with water, and brine, dried over magnesium sulfate, and evaporated. The residue was recrystallized from ethyl acetate to obtain the compoumd (B1) 370 mg.
