반응 단계

236.1 g (0.75 mol) 2-Chloroethyl 2-(methoxyacetyl)-2-(2,6-dimethylphenyl)-hydrazinecarboxylate, 375 ml xylene and 187 ml water are stirred with external cooling, while 82.5 ml (0.82 mol) of an aqueous solution of sodium hydroxide (containing ~0.4 g NaOH per ml) are added at a rate to maintain the internal temperature at approx. 20°. The mixture is stirred after completion of the addition for 1 hour at 20°, and for 2 hours at 0°. The solid is filtered off, washed with 150 ml water and dried to yield the title compound as a slightly coloured solid, m.p. 102°-103°.
