Versuchsvorschrift

A mixture of 1-(2-bromomethyl-3-cyclopropylphenyl)-4-methyl-1,4-dihydrotetrazole-5-one 0.30 g, 2-methyl-4-(1-methyl-1H-pyrazol-3-yl)-phenol (described in Reference Preparation example 29) 0.18 g, potassium carbonate 0.18 g and acetonitrile 10 ml was stirred with heating under reflux for four 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-(1-methyl-1H-pyrazol-3-yl)-phenoxymethyl]-phenyl}-4-methyl-1,4-dihydrotetrazole-5-one (hereinafter, referred to as “Present compound 12”) 0.22 g.
