実験手順

To a suspension of 2-chloro-3,4-dihydro-6-(3,4-dimethoxyphenyl)-3-methyl-4-(2,4,6-trimethylphenylimino)pyrimidine (10.0 g) in chloroform (100 ml) was added hydrazine hydrate (3.66 ml). The mixture was refluxed for 6 hours. The reaction mixture was evaporated in vacuo. The residue was chromatographed on silica gel using chloroform to give 3,4-dihydro-6-(3,4-dimethoxyphenyl)-2-hydrazino-3-methyl-4-(2,4,6-trimethylphenylimino)pyrimidine (3.46 g).
