Reaction Steps

To a solution of ethyl 3-oxo-4-(4-((2-phenoxybenzyl)oxy)phenyl)butanoate (40 mg) in 1,4-dioxan (0.12 ml), 9 mg of hydroxylammonium chloride and 0.1 ml of 2.5N sodium hydroxide were added under ice-cooling, and the reaction solution was stirred at 0° C. for 1.5 hours. Concentrated hydrochloric acid (0.07 ml) was further added, and the reaction solution was stirred at room temperature for 20 minutes. The reaction solution was extracted with chloroform, the combined organic layers were washed with a saturated saline solution and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue obtained was purified by preparative thin layer chromatography (Kieselgel™ 60 F254, Art5744, made by Merck & Co., hexane/ethyl acetate (1:1) to afford the title compound as a yellow oil.
