実験手順

To a stirred solution of 1-methyl-6,7-dimethoxy-3,4-dihydroisoquinoline in acetone was added methyl iodide and the reaction mixture was stirred at room temperature for 16 hours. A bright yellow precipitate formed. The by-products and methyl iodide were removed in vacuo to afford the desired compound in 95% yield.
