Aluminium lithium hydride → N-(8-methoxytetralin-2-yl)-N-propyl-N-[2-(2-thienyl)ethyl]amine

Participants

Reaction Steps

To a solution of 16 mg (0.05 mmol) of N-(8-methoxytetralin-2-yl)-N-propyl-2-(2-thienyl)acetamide (A4-1: R═OMe, Cy=2-thienyl) in 10 mL dry diethyl ether 0.15 mL of a 1 M solution of LiAlH4 (0.15 mmol) in dry diethyl ether were added dropwise and stirred for 20 hrs at room temperature. The reaction was terminated by adding a saturated aqueous solution of sodium hydrogen carbonate, the solution was filtered through a matrix consisting of Celite™ —MgSO4—Celite™ and subsequently washed with methylenchloride and ethyl acetate. After evaporating the organic solvents in vacuo the residue was purified by flash chromatography on silica gel with a mixture of hexane/ethyl acetate 10/1 in the presence of 0.5% (v/v) dimethylethylamine to get compound (N-(8-methoxytetralin-2-yl)-N-propyl-N-[2-(2-thienyl)ethyl]amine (A5-1: R═OMe, Cy=2-thienyl)).
