Reaction Steps

N-[3-(1-Acetyl-6-methyl-1H-pyrazolo[3,2-c]-s-triazol-3-yl)-4-methoxyphenyl]-2-hydroxy-5-(4-methoxyphenylazo) benzamide (1.4 g) was dissolved in methanol (100 ml) and a solution of sodium hydroxide (1.0 g) in water (30 ml) added. After stirring for 15 minutes the solution was acidified with glacial acetic acid when a gelatinous precipitate of the product appeared. This was removed by filtration, washed with water and crystallized in aqueous pyridine (850 mg; 66%), m.p. 295°-6°, λmax (methanol)=350 nm.
