Abstract

C 14 H 11 N 3 O, triclinic, P1 (no. 2), a = 9.0506(8) Å, b = 11.362(1) Å, c = 11.486(1) Å, a = 88.137(7)°, b = 87.526(7)°, g = 89.659(7)°, V = 1179.4 Å 3 , Z = 4, Source of materialTo 3,7 g (16,46 mmol) of 2-amino-N'-phenyl hydrazine [7], 22 ml of triethyl orthoformate were added. The reaction mixture was refluxed for 5 hours. Thereafter, the mixture is cooled, and the precipitate formed was crystallized from methanol, obtaining 3.26 g (yield 87%
