Reaction Steps

At room temperature, to 28%-Ammonia solution 50 ml was added 5-{4-[2-Cyclopropyl-6-(4-methyl-5-oxo-4,5-dihydro-tetrazol-1-yl)-benzyloxy]-3-methyl-phenyl}-2,4-dimethyl-2H-pyrazole-3-carbonyl chloride (described in Reference Preparation example 117) 1.3 g. The mixture was stirred for twelve hours and concentrated under reduced pressure and added 10%-hydrochloric acid solution 10 ml. The precipitates were filtrated and were washed with water and were dried under reduced pressure to give 1-{3-cyclopropyl-2-[2-methyl-4-(5-aminocarbonyl-1,4-dimethyl-1H-pyrazol-3-yl)-phenoxymethyl]-phenyl}-4-methyl-1,4-dihydrotetrazole-5-one (hereinafter, referred to as “Present compound 49”) 0.8 g.
