실험 절차

To a THF solution containing the α-(2-furyl)aminoacetonitrile (2.15 g) and triethylamine (1.75 g) was added 1-methyl-1H-pyrazole-4-carboxylic acid chloride (2.55 g) under cooling with ice, and the whole was stirred for 1 hour as such and then for 16 hours at room temperature. The solid product formed was taken out by filtration, and the solvent was evaporated out, and then the thus-obtained oily product was purified by column chromatography and then washed with isopropyl ether, to give 2.55 g of the intended N-(cyano-2-furanylmethyl)-1-methyl-1H-pyrazole-4-carboxamide crystal.
