Procedure
17 g of N-(1-benzylpiperid-4-yl)-N'-tert-butylthiourea are added to 170 ml of 33% hydrobromic acid in acetic acid; the reaction mixture is stirred at room temperature for 4 hours, then it is poured over diethylether. The crystals obtained are filtered and they are thoroughly washed with diethylether in order to obtain white crystals which melt at 120° C.; yield: quantitative.
