    • In a typical procedure, the oxime (0.3-1 mmol) was dissolved in the IL (about 1 mL) and added, under stirring, with the appropriate quantity of cyanuric chloride (TCT, 2 or 20 mol, The mixture was left at the desired temperature (60°C or 130°C) and monitored by TLC (eluant EtOAc-light PE) until completion. The amide was isolated by direct chromatography (silica gel) of the reaction mixture (eluant EtOAc-light PE, Alternatively, the mixture was extracted with MTBE (4 x 3 mL) and concentrated under vacuum. The crude was purified on silica gel column to afford the pure product. The amide was identified (1H NMR) by comparison with the authentic sample. The residue of the IL was dissolved in CH2Cl2, filtered on Celite, and reused after removal of the organic solvent under vacuum
