Procedimiento

To a solution of pyrrolidine-1-carboxylic acid 4-hydroxy-cyclohexylmethyl ester (1 mmol) in methylene chloride (5 mL) were added picolinoyl chloride (1.1 mmol) and triethylamine (1.5 mmol) and the resulting mixture was stirred for 16 hours at room temperature. The reaction mixture was diluted with water, followed by few times of extraction with methylene chloride. The combined organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, ethyl acetate), thereby completing the preparation of a target compound (233 mg, 70% yield).
