실험 절차

A solution of ethyl(4-{4-[5-(4-tert-butylphenyl)-4-methyl-4H-[1,2,4]-triazol-3-yl sulfanyl]-2-heptyloxybenzylamino}phenyl)acetate obtained in Example 1 (2.5 g, 4 mmol) of a 2M aqueous potassium carbonate solution (32 ml) in methanol (65 ml) is heated under reflux for 3 hours. The organic phase is acidified at room temperature with a 2N hydrochloric acid solution to pH 5. The desired product is extracted by addition of ethyl acetate. The organic phase is washed with water, dried with magnesium sulfate and concentrated using a rotary evaporator. The product is purified by chromatography on a silica column, eluted with a heptane/ethyl acetate 4:6 mixture. After evaporation of the solvents, 1.7 g (70%) of the expected compound are recovered in the form of a yellow amorphous solid.
