Procedures for the synthesis of Fursultiaminum have been developed, especially in the synthesis of sodium tetrahydrofurfuryl thiosulfate(R 1SSO 3Na) and in the reaction between open chain VB 1 and R 1SSO 3Na A good yield of 76 5% with low cost was obtained The new synthesis method is fit fo industry
