With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2682-49-7,Thiazolidin-2-one,as a common compound, the synthetic route is as follows.,2682-49-7

Thiazolidinone (3.43 g, 29.32 mmol) and POBr3 (25 g, 87.96 mmol, 3 equiv.) are mixed under nitrogen as solids. The reaction mixture is then heated to HO0C under stirring for 3 h causing the formation of a black syrup. The reaction mixture is then allowed to cool down to room temperature and a mixture of water/ice (200 mL) is added very cautiously. The resulting grey suspension is extracted with diethyl ether (3 x 50 mL), the organic layers are combined, filtered through a silica plug and evaporated to afford the title compound as an orange oil (4 g, 57%) which is used in the next step without further purification.
