Reaction Steps
A solution of 8.2 g. (0.1 mole) dimethylamine hydrochloride in 8 ml. formalin is added dropwise to 17.12 g. (0.1 mole) of 1-benzylpyrrole. The mixture is stirred at room temperature until solution occurs (about 4 hours). The solution is poured into 10% sodium hydroxide solution and then extracted into ether three times. The combined organic fractions are washed with a saturated solution of sodium chloride, dried over magnesium sulfate and the solvent evaporated in vacuo. The product, 2-dimethylaminomethyl-1-benzylpyrrole, is distilled at reduced pressure, b.p. 73° C., 0.025 mm. Hg.
