실험 절차

A mixture of 1,3,5-trichlorobenzene (2.53 g), hydrazine hydrate (3.48 g, 5 molar equivalents) and pyridine (12 ml) was heated in an autoclave (purged with argon) for 6 hours at 180° C. The mixture was cooled, the excess hydrazine decanted and the organic phase evaporated in vacuo to give the title compound in 60% yield. It was shown that 65% of the starting material had been consumed, thus indicating that the reaction had occurred with high selectivity.
