The flask was immersed in a NaCl / ice bath and 40% wt. aqueous dimethyl amine (7.1 ml, 56 mmol) was added at once with 0 stirring. To this cooled solution was added a solution of 5-bromoindole (10.0 g, 51.0 mmol) in 1,4-dioxane (52 ml) at a rate such that the reaction temperature did not exceed 0 0C. Stirring was continued for 2 h after which time the reaction mixture was removed from the ice bath and allowed to stir overnight (12 h) at room temperature. The reaction mixture was diluted with 5 H2O (640 ml) then charcoal (~ 3 g) and Celite (~3 g) were added. The mixture was stirred 10 min and then filtered. To the filtrate was added 2 M NaOH (500 ml) with stirring. The resulting precipitate was filtered under vacuum and the filter cake washed with water (3 x 200 ml).
