실험 절차

A mixture of 17.7 g (0.1 mol) 2,6-dimethylphenylhydrazine hydrochloride, 21.2 g (0.2 mol) sodium carbonate in 50 ml water and 50 ml xylene are stirred for 30 minutes at room temperature, then cooled to 5°. 14.3 g (0.1 mol) chloroformic acid 2-chloroethylester is then added over a period of 1 hour, the temperature being maintained at 5°. The mixture is stirred at 5° for another hour, at the end of which 100 ml water are added, the precipitate thus formed filtered off, washed with water and dried. Further work-up as in Example 1b.
