To a solution of hydrazonoyl bromide (5.70 g, 0.02 mol) 2 and 1 [1] (3.18 g, 0.01 mol) in tetrahydrofuran (60 ml) was added triethylamine (2.02 g, 0.02 mol in 10 ml of THF). The reaction mixture was refluxed for 48 hours. The solvent was evaporated under reduced pressure and the resulting crude material was chromatographied over silica gel column using 10:90 ethylacetate:hexane as eluent (yield 70%).
Melting point: 182-184°C
IR (KBr , cm−1 ): 1640 (nN-C=O); 1720 (nN-C=O).
