27% | In ethanol; at 20℃; | General procedure: Compounds 2 were prepared by the reaction between <strong>[7504-94-1]2-hydrazinylpyrimidine</strong> 1 (0.04 g, 0.36 mmol) and the appropriate aromatic or heteroaromatic aldehyde (1.0 eq., 0.36 mmol) in ethanol (3.0 mL) [27]. The reaction mixture was stirred for between 20 min and 5 h at room temperature. After rotary evaporation, the product was purified by washing with cold ethanol (2.0 mL) and cold diethyl ether (2.0 mL), leading to the pure derivatives 2a-f as solid in 27-75% yields. |

76% | In methanol; for 24.0h;Reflux; | General procedure: The ligands H6L1-7 were prepared by similar methods. A representativemethod for I is presented here. A solution of salicylaldehyde(1.46 g, 12 mmol) in MeOH (30 mL) was added to amethanolic suspension of <strong>[36997-31-6]benzene-1,3,5-tricarbohydrazide</strong>(0.504 g, 2 mmol). The reaction mixture was refluxed on an oilbath. During this period, the <strong>[36997-31-6]benzene-1,3,5-tricarbohydrazide</strong>slowly dissolved and simultaneously a white solid precipitated.After 24 h of reflux, the reaction mixture was cooled at room temperaturefor an hour, the precipitated solid was filtered, washedwith MeOH (2 5 mL) and dried in a desiccator over silica gel.Data for H6L1 (I): Yield 0.954 g (85%).
