Procedure

To 150 ml of ethyl acetate were added 5.0 g of 1-(O-isopropyl-3-benzyloxybenzohydroximoyl)-1H-1,2,4-triazole (melting point: 62° C. to 67° C.) and 1 g of 10% palladium carbon at room temperature. In connection with the mixture, the hydrogenolysis reaction was carried out. After 8 hours, the palladium carbon was removed. The filtrate was then concentrated. The residue was purified by column chromatography, thus yielding 3.2 g (yield: 89%) of the desired product having a melting point of 160° C. to 163° C.
