Participants

Reaction Steps

To a solution of Ethyl 5-hydroxy-2-methyl-4-[3-[3-propyl-6-(trifluoromethyl)benzothiophen-2-yl]propionyl]-phenoxyacetate (obtained in Example 22-(4), 19 mg, 0.0381 mmol) in EtOH (0.4 mL) was added hydroxylamine hydrochloride (2.9 mg, 0.0419 mmol) and sodium acetate (3.8 mg, 0.0457 mmol) in water (0.3 mL). The mixture was heated for 10 hours under reflux and cooled to room temperature, diluted with water, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was recrystallized from chloroform-hexane, to give the titled compound as a white crystal (7.5 mg, yield 38%).
