Participants

Reaction Steps

There was dissolved, in ethanol (2 mL), trifluoroacetic acid salt of (7-morpholin-4-yl-2-phenyl-pyrazolo[1,5-a]pyrimidin-5-yl)-hydrazine (25.0 mg, 0.0464 mM), then 4-hydroxy-benzaldehyde (6.2 mg, 0.051 mM) was added to the solution and the mixture was stirred at room temperature for one hour. This reaction liquid was filtered and the resulting solid was purified by the NH-silica gel column chromatography (methanol/methylene chloride=1/20) to thus give the title compound (19.2 mg, yield: quantitative).
