Compound can be prepared in several related ways: 1) The condensation of N-(1-phenylisopropyl)methylamine (I) with 1,2-dibromopropene (A) by heating at 100 C gives N-(1-phenylisopropyl)-N-methyl-2-bromopropenylamine (II), which is then dehydrobrominated and isomerized by treating with KOH in refluxing ethanol water. 2) By heating a mixture of (I) and propargyl bromide (B) at 100 C. 3) By reductocondensation of (I) with propargyl aldehyde (C) by means of amalgamated Al in ethanol. 4) By condensation of (I) with formaldehyde and acetylene by means of CuCl in hot dioxane. 5) By condensation of 1-phenylisopropyl chloride (III) with N-methylpropargylamine (IV) by heating at 80 C in a sealed tube.
