The product 2 was prepared by the addition of p-phenylendiamine (NH2C6H4NH2) to 1 [1] according to the reported procedure [2]. To a solution of 1 (3.4 g, 20 mmol) in acetonitrile (45 ml) was added p-phenylendiamine (0.54 g, 5 mmol) and the mixture was stirred. The stirring was continued at room temperature for a week. The residue was precipitated by addition of cold water, purified and dried by hexane and under vacuum, to afford 2.63 g (74% yield) 2 as a white solid.
Melting Point: 197 °C.
IR (KBr, cm–1): 3140 (=CH), 2990 (CH), 1730 (C=O), 1540 (C=C), 1480 (-C=N), 1450, 1410.
1H-NMR (400 MHz, CDCl3): δ= 7.25 (s, 4H, Ph); 6.5 (s, 4H, Pyrazol); 5.6 (s, 8H, N-CH2-N); 4 (s, 12H, O-CH3); 2.2 (s, 12H, CH3).
MS (m/z): 739 [M + Na+]; 716 [M]+; 613; 585; 460.
