87% | at 190℃; for 2h;Ionic liquid; | General procedure: The solution or suspension of the imidate 2 (2 mmol) in 2 g of corresponding IL was heated at corresponding temperature (see Table 2) and stirred until disappearance of the reactant (TLC monitoring, eluent CH2Cl2). Then the reaction mixture was cooled to room temperature, CH2Cl2 (1.5 ml) wasadded and the obtained N,N-diarylbenzamide 1 was extracted with Et2O (5×10 ml). The ethereal extract was stirred with 1 g of absorbent carbon, filtered, Et2O was evaporated from the filtrate in vacuo and the residue was crystallized from corresponding solvent. The IL was dried in vacuo from the solvents remainders and repeatedly used several time in the next syntheses of the same product without lowering the yield. |
