3-[4-(1-Piperidinylmethyl)phenoxy]-1-propanamine → 1-Methyl-3-(methylthio)methyl-N-[3-[4-(1-piperidinylmethyl)phenoxy]propyl]-1H-1,2,4-triazole-5-amine

Participants

Reaction Steps

Methyl N-[2-(methylthio)acetyl]-1-methyl-2-(phenylmethylene)hydrazine carboximidothioate (1.2 g) and 3-[4-(1-piperidinylmethyl)phenoxy]propanamine (0.9 g) were heated at 55° under water vacuum for 2 h. Additional carboximidothioate (0.09 g) was then added and the mixture heated for a further 1 h. The reaction mixture was dissolved in toluene (5 ml) and 5N hydrochloric acid (4 ml), stirred at room temperature for 18 h and the phases separated. The aqueous phase was basified to pH 10 with sodium carbonate and extracted with ethyl acetate to give an oil, which was chromatographed using ethyl acetate-methanol (3:1) to give the title compound (1.04 g) as an orange brown oil.
