実験手順

A mixture of 2-methyl-3-trimethylammoniomethylimidazo[2,1-a]isoquinoline methylsulfate (4.5 g) and imidazole (2.02 g) in ethanol (45 ml) was refluxed with stirring for 7 hours and evaporated in vacuo. To the residue was added water and the resulting precipitates were collected by filtration and recrystallized from a mixture of ethyl acetate and n-hexane to give 3-(1-imidazolylmethyl)-2methylimidazo[2,1-a]isoquinoline (2.3 g).
