    摘要: A process is disclosed for the preparation of 7-amino-3-(2-furanylcarbonylthiomethyl)-3-cephem-4-carboxylic acid (also known as Furaca). The process comprises of the steps of reacting 7-aminocephalosporanic acid with a mixture of 2-thiofuric acid and Boron Trifluoride in a solvent and precipitating Furaca as a solid.
