实验过程
A mixture of 2.9 g of 2-nitroiminothiazolidine, 2.9 g of anhydrous potassium carbonate, 3.2 g of 2-chloro-5-pyridylmethylchloride and 50 ml of acetonitrile was refluxed for 5 hours with vigorously stirring. After the reaction, most of the acetonitrile was removed by distillation and water was added to the residue. As the solid product was separated, it was collected by filtration. The crude material was recrystallized from ethanol to give desired 3-(2-chloro-5-pyridylmethyl)-2-(nitroimino)thiazolidine.
