Versuchsvorschrift

A mixture of 1-(2-bromomethyl-3-cyclopropylphenyl)-4-methyl-1,4-dihydrotetrazole-5-one (described in Reference Preparation example 2) δ0 g, 2-methyl-4-(3,4,5-trimethyl-pyrazol-1-yl)-phenol (described in Reference Preparation example 20) 0.36 g, potassium carbonate 0.29 g and acetonitrile 15 ml was stirred with heating under reflux for seven hours. After cooling to room temperature, the reaction mixture was filtered, and the filtrate was then concentrated. The resulting residue was subjected to a silica gel column chromatography to give 1-{3-cyclopropyl-2-[2-methyl-4-(3,4,5-trimethyl-pyrazol-1-yl)-phenoxymethyl]-phenyl}-4-methyl-1,4-dihydrotetrazole-5-one (hereinafter, referred to as “Present compound 2”) δ1 g.
