실험 절차

A solution of 60 mg (0.27 mmol) of the free base of N-(8-methoxytetralin-2-yl)-N-propylamine (A2-1) and 0.11 mL Et3N (0.79 mmol) in 5 mL dry CHCl3 was cooled in an ice bath. After adding 0.05 ml (0.41 mmol) 2-thienylacetic acid chloride (A3-1: W=Cl, Cy=2-thienyl) to the mixture the ice bath was removed and the reaction was stirred for 2 hrs at room temperature. In a second step further 0.05 mL (0.41 mmol) of 2-thienylacetic acid chloride (A3-1) were added and the reaction stirred for 20 hrs. The mixture was washed with a saturated solution of aqueous NaHCO3 for several times and finally extracted with CH2Cl2. The organic layers were dried over MgSO4 and the solvent was evaporated in vacuo. Flash chromatography of the residue on silica gel with a mixture of hexane/ethyl acetate 40/1 gave the product N-(8-methoxytetralin-2-yl)-N-propyl-2-(2-thienyl)acetamide.
