Procedure
1.45 g of ammonium thiocyanate are dissolved in 30 ml of acetone and after 2.2 ml of benzoyl chloride have been added, the reaction mixture is heated under reflux for 15 minutes. 2.6 g of 6-amino-7-methoxy-1,2,3,4-tetrahydronaphthalene (Compound 4-1) dissolved in 20 ml of acetone are added and then the mixture is heated under reflux for 30 minutes. It is evaporated to dryness, the residue obtained is taken up in a minimum of ethanol, 50 ml of 30% ammonium hydroxide are added and the mixture is heated under reflux for 20 hours. The thiourea obtained is cooled, filtered, washed with waer and then with an ethyl acetate/hexane 25/75 (v/v) mixture. 2.8 g of the expected product are obtained in the form of a beige powder; yield=80%.
