실험 절차

To a stirred solution of 1,2,3,4-tetrahydro-6,7-dimethoxy-1-methylisoquinoline (20.0 g, 0.097 m) and triethylamine (9.8 ml, 0.097 m) in chloroform (200 ml) under nitrogen was added dropwise a solution of 4-acetoxyphenylacetyl chloride (20.3 g, 0.097 m) in 50 ml chloroform and the mixture stirred at ambient temperature for 16 hours. The mixture was washed with 10% HCl (3×200 ml), water (200 ml), saturated sodium carbonate (3×150 ml) and water (200 ml) and the chloroform layer dried over MgSO4. Evaporation of the solvent afforded 33.0 g of N-(4-acetoxyphenylacetyl)-1,2,3,4-tetrahydro-6,7-dimethoxy-1-methylisoquinoline as a pale yellow oil (89% yield).
