Mode opératoire

A mixture of 1-(2-methoxymethyl-3-ethenylphenyl)-4-methyl-1,4-dihydrotetrazole-5-one described in Reference Preparation example 2219.7 g, palladium fibroin complex 3.02 g and methanol 1 L was stirred at room temperature under hydrogen atmosphere for eleven hours. The reaction mixtures were filtered and the filtrates were concentrated under reduced pressure. The resulting residues were subjected to a silica gel column chromatography to give 1-(2-methoxymethyl-3-ethylphenyl)-4-methyl-1,4-dihydrotetrazole-5-one 19.3 g.
