実験手順
A solution of 7 g of 4-(2-chloronicotinoyl)-2,6-di-tertiary butylphenol and 2.4 g of phenylhydrazine in 40 ml of pyridine is refluxed for 7 hours. After the pyridine is distilled off under reduced pressure, to the residue is added water and the precipitated crystals are washed with water to give crude crystals of 4-(2-chloronicotinoyl)-2,6-di-tertiary butylphenol phenylhydrazone, melting at 181° C. with decomposition in an almost quantitative amount.
