実験手順
In 8 ml of toluene, 229 mg (1.00 mmol) of 5-amino-3-(3-nitro-phenyl)-1H-pyrazole-4-carbonitrile and 317 μl of N,N-dimethylformamide dibenzylacetal are boiled overnight. Cooling, filtering the suspension and washing with hexane yield N'-[3-(3-nitrophenyl)-4-cyano-1H-pyrazol-5-yl]-N,N-dimethylformamidine; m.p. 221-225° C.; TRet (Grad22-100)=8.7.
