Procedure

5 g (41 mmol) of 2-amino-3-methylphenol and 6.51 g (41 mmol) of potassium O-ethyl dithiocarbonate, in suspension in 70 ml of ethanol, are successively introduced into a 500 ml round-bottomed flask and the mixture is heated at reflux for 24 h. The solvent is removed by evaporation under reduced pressure, the residue is taken up-in 50 ml of water and 4 ml of acetic acid are added. The precipitate obtained is filtered off, rinsed with water and dried under vacuum.
