Participants

Reaction Steps

To a solution of 42 mg of t-butyl 4-((2R)-2-((1R)-3,3-difluorocyclopentyl)-2-hydroxy-2-(4-(hydroxymethyl)phenyl)-ethanoyloxy)tetrahydropyridine-1(2H)-carboxylate in 2 ml of chloroform, 0.015 ml of triethylamine, 0.01 ml of acetic anhydride and 2 mg of dimethylaminopyridine were added successively, followed by an hour's stirring at room temperature. The reaction liquid was diluted with ethyl acetate, washed successively with water and saturated brine, and dried over anhydrous sodium sulfate. Distilling the solvent off under reduced pressure, the resulting residue was purified on preparative thin layer chromatography (Kieselgel™ 60F254, Art 5744 (Merck), hexane/ethyl acetate=2/1) to provide 42 mg of the title compound as a colorless oily substance.
