A solution of 1.0 g (5 mmol) of 3-nitrosalicylohydrazide in 50 ml of anhydrous ethanol were treated with 0.6 g (5 mmol) of acetophenone and with a catalytic amount of p-toluenesulfonic acid. After the mixture had been stirred for 14 hours at approximately 20 to 25° C. and the solvent had been distilled off, 1.4 g of the title compound (90% of theory) were obtained as colorless crystals of m.p.: 163-168° C.
