专利号:US-2003181713-A1 优先权日:2002-03-04 标 题:Processes for the synthesis of chloroadenosine and methylthioadenosine 发明人:SRIRANGAM JAYARAM KASTURI; SAENZ JAMES EDWARD 摘要:An in situ process for preparing chloroadenosine is described, wherein adenosine in a non-aqueous solvent is reacted with a thionyl chloride and a pyridine to form a reaction solution; the non-aqueous solvent is exchanged with a lower alcohol, and a base is added to the reaction solution; and the resulting chloroadenosine is filtered, washed and dried. Additionally, a two-step process for the synthesis of methylthioadenosine using the chloroadenosine prepared in situ is described.
