Versuchsvorschrift

N-methyl-p-toluidine, 29.3 g, and methanol, 50 g, were placed in a reactor. Propylene oxide, 25.4 g, was slowly added to the reactor over two hours. Afterwards, the reactor was heated under reflux for 6 hours. The low boilers were removed by distillation. Then, the mixture was vacuum distilled to give 2HPMT. The boiling point is 92° C. at 5 mm Hg.
