Versuchsvorschrift
3-Dimethylamino-2-(2-nitrophenyl)propenal (Maybridge) in ethanol was treated with hydrazine via syringe and heated to reflux for 16 hours. Concentration in vacuo afforded crude 4-(2-nitrophenyl)pyrazole, which was reduced as in Example 64 and coupled with CMI to give the fumaric acid salt of N-(4,5-dihydro-1H-imidazol-2-ylmethyl)-2-(1H-pyrazol-4-yl)aniline.
