77% | General procedure: A mixture of the corresponding dicarboxylic acids (3.4 mmol) and <strong>[1937-19-5]aminoguanidine hydrochloride</strong> (1.88 g, 17 mmol) in water (2 mL) was irradiated in a 10 mL seamless pressure vial using microwave system operating at maximal microwave power up to 300 W at 220 C for 15 min. After cooling to the ambient temperature, 1 mL of 17 M aq. NaOH solution was added to the vial and the reaction mixture was irradiated again at 200 C for 10 min. After cooling to the ambient temperature, the precipitated solid was filtered, washed with cold water and recrystalised from water to give desired products 6, 11-17. The reaction was also replicated in an increase scale of dicarboxylic acids (17 mmol) and <strong>[1937-19-5]aminoguanidine hydrochloride</strong> (9.40 g, 85 mmol) increasing the base and solvent quantities proportionally. |
