Reaction Steps

To a solution of 8-bromo-1-methyl-2-tetralone (4.05 gm, 16.9 mMol) in dichloromethane (60 mL) were added magnesium sulfate (3.0 gm, 25 mMol) and n-propylamine (2.0 mL, 24.4 mMol). The mixture was stirred at room temperature for twenty hours. The reaction mixture was filtered through a bed of celite and the filtrate concentrated in vacuo to give 1-methyl-2-n-propylimino-8-bromo-1,2,3,4-tetrahydronaphthalene as a dark residue.
