The product 2 was prepared by the addition of benzylamine (C6H5CH2NH2) to 1 [1] according to the reported procedure [2]. To a solution of 1 (1.26 g, 10 mmol) in acetonitrile (25 ml) was added benzylamine (0.536 g, 5 mmol) and the mixture was stirred. The stirring was continued at room temperature for 4 days. The residue was precipitated by addition of cold water, purified and dried by hexane and under vacuum, to afford 2 as a white solid (1.08 g, 63%).
Melting point: 72 °C.
IR (KBr, cm–1): 3262 (= C-H aromat); 3080 (CH); 1603 (C=C); 1500, 1472 (C=N); 1507; 1351; 1290; 1230.
1H-NMR (400 MHz, CDCl3): δ= 7.4 (s, 5H, Ph); 5.9 (s, 2H, Pyrazol); 5 (s, NCH2N); 3.9 (s, 2H, Ph-CH2-N); 2.3 (s, 6H, CH3); 2.1 (s, 6H, CH3).
MS (DCI/NH3, CHCl3) = Calculated for [M]+, C19H25N5= 323. Found 324 ([M+H]+, 92.5%); 228 ([MH – C5H7N2]+, 100%); 114 ([C5H7N2+NH4]+, 42.5%).
