実験手順

To 70 mL of sulfuric acid at 10° C. is added portionwise sodium nitrite (7 g, 0.1 mol). The reaction mixture is warmed to 20° C. to dissolve all the sodium nitrite and then cooled to 15° C. To the reaction mixture is added over 30 minutes a suspension of 3-nitro-4-amino-1,1′-biphenyl (7.33 g, 0.034 mol), prepared in (B) above, in 60 mL of acetic acid. The reaction mixture is stirred for one hour at 10° C. and then to the reaction mixture is added 500 mL of diethyl ether. An exotherm occurs. The mixture is stirred for one hour. The solid formed is removed by filtration behind a safety shield and washed with diethyl ether to give 16.2 g of the title compound as a yellow solid. The solidis dried for 1.5 hours at 20° C. under vacuum and stored in a freezer in a polyethylene container until later use. Analysis: IR (nujol) v 1650 (N═N), 2250 (N2+) cm−1.
