Mode opératoire

In 7 mL of ethyl acetate was dissolved 0.31 g of 1-{3-[2-(1-benzothiophen-5-yl)ethoxy]propyl}-3-azetidinyl=methyl=carbonate, and to the solution was added a solution of 0.10 g of oxalic acid in 1 mL of ethyl acetate, after which the resulting mixture was stirred at room temperature. The crystals precipitated were collected by filtration to obtain 0.34 g of 1-{3-[2-(1-benzothiophen-5-yl)ethoxy]propyl}-3-azetidinyl=methyl=carbonate oxalate.
