実験手順: Homoveratrylamine (13.6 g, 0.0753 mole) and o-methylstyrene oxide (10.1 g, 0.0753 mole) were stirred at 100° under argon for 16 hours and then diluted with benzene and hexane and cooled in ice. The solid which precipitated was filtered and recrystallized from benzene-hexane to give 8.6 g (36%) of 2-methyl-α-[N-(3,4-dimethoxyphenethyl)aminomethyl]benzyl alcohol, mp 91°-94°. cooled in ice The solid which precipitated was filtered recrystallized from benzene-hexane

実験手順: Sodium hydride (57%) (4.84 g., 0.115 mole) previously washed with hexane was stirred with dry dimethylsulfoxide (70 ml) at 65°-70° for 2 hours under argon. The mixture was diluted with dry THF (70 ml), cooled to -5° and trimethylsulfonium iodide (23.5 g, 0.115 mole) in 100 ml of dry DMSO was added over a period of 3 minutes. After stirring for one minute o-tolualdehyde (11.5 g, 0.0926 mole) was added at a moderate rate while keeping the reaction mixture at 0° to -5°. The mixture was stirred at 0° for 5 minutes and at room temperature for 1 hour, diluted with 500 ml of ice water and extracted three times with ether. The ether solution was washed with saturated sodium chloride, dried with sodium sulfate and evaporated to an oil which was distilled under reduced pressure (~0.25-0.50 mm) to give 10.25 g (83 %) of o-methylstyrene oxide as a clear liquid (b.p. 35°-38°). cooled to -5° was added at a moderate rate at 0° to -5° extracted three times with ether The ether solution was washed with saturated sodium chloride dried with sodium sulfate evaporated to an oil which was distilled under reduced pressure (~0.25-0.50 mm)
