    • Substances were purchased commercially and used without further purification. Some of the starting materials remain which may be removed by washing of the mixture with a solution of NaHCO3 (except in the case 3d, Also, a little of unknown by-products was obtained which must be separated by chromatography. The reactions were carried out in DMF as an excellent polaraprotic solvent with high boiling point. Also, DMF is soluble in water; therefore, in the work-up process, it is simple to remove the solvent and the residual semicarbazide hydrochloride by washing of the reaction mixture in water. General reaction procedure: A mixture of 1 mmol of an anthranilic acid derivative 1a-1e, 0.123 g (1.1 mmol) of semicarbazide hydrochloride and 1 mL of DMF in a 10 mL flask was refluxed for the times as indicated in Table 1. The mixture was washed with cold-water (three times, The solid residue was washed two times with a 10% solution of NaHCO3 except in
