Reaction Steps
Cyclopropanecarboxylic acid chloride (0.49 g) in dry ether (10 ml) is added to a solution of cis-5-methoxy-1-methyl-2-(N-cyclopropylmethylamino)tetralin (400 mg) and triethylamine (0.49 g) in dry ether (80 ml). After 30 minutes at room temperature the reaction mixture is filtered and the ether is evaporated. The resulting crude amide is passed through an alumina column eluted with ether. The purified amide dissolved in dry THF (20 ml) is added to a suspension of lithium aluminum hydride (1.0 g) in dry THF (30 ml) under N2. After stirring under reflux for 3 hours, the reaction mixture is hydrolyzed, the precipitate is filtered off and the solvent is evaporated. The oily residue is chromatographed on an alumina column with ether-light petroleum (1:1). The hydrochloride is prepared and recrystallized from ethanol-ether to give the title compound.
