실험 절차

33.6 g (0.2 mole) of 2-aminonaphthalene-1-carbonitrile (cf. Example 1) in 250 ml of absolute acetonitrile were added at 65° C. to a suspension of 32.3 g (0.24 mole) of copper(II) chloride (anhydrous) and 30.9 g (0.3 mole) of tert-butylnitrile in 800 ml of absolute acetonitrile. After the end of gas evolution, 2,000 ml of 20% strength hydrochloric acid were added to the cooled reaction mixture, and the precipitate was isolated, washed and dried. 31.7 g (70% of theory) of the title compound of melting point 82°-83° C. (active ingredient example 1001) were obtained in this manner.
