Participants

Reaction Steps

A mixture of 20.6 ml. (0.24 mole) 37% aqueous formaldehyde, 18 ml. (0.12 mole) 40% aqueous dimethylamine and 80 ml. acetic acid is cooled to 0° and treated by dropwise addition with 25.5 g. (0.113 mole) 2-(5-methyl-3-phenyl-4-isoxazolyl)-indole in a solution of 45 ml. acetic acid and 125 ml. dioxane. After addition is complete the mixture is stirred for 1 hour at room temperature and poured onto 500 ml. ice-water. The resulting solution is made basic with 20% potassium hydroxide and then extracted with methylene chloride. The methylene chloride is washed with water, brine, dried over anhydrous magnesium sulfate, filtered and evaporated to give 2-(5-methyl-3-phenyl-4-isoxazolyl)-3-(dimethylaminomethyl)-indole.
