Methyl iodide → 2-(2-Methoxy-4-methylphenyl)-1H-indole

Participants

Reaction Steps

At a temperature of 25° C. 54 g (1 mol) of sodium methylate and 170 g (1.2 mol) of methyl iodide were added to a solution of 223 g (1 mol) of 2-(2'-hydroxy-4'-methyl-phenyl)-indole, prepared as in Example 1, in 1200 ml of N,N-dimethylformamide. The solution was then stirred for 2 hours and the crude product was precipitated by adding water. After recrystallization from benzene, 166 g of 2-(2'-methoxy-4'-methyl-phenyl)-indole were obtained. M.P.: 125° C. Yield: 70%.
