The method is characterized in that:(1) the reflux of the 2-[N, N- 2amino]-3-cyano-group-4-thiopheneacetic-5-carboxylic acid tetra ester is carried out in the proper sodium hydroxide aqueous solution of alcohol for 5h to 6h and the pH value is kept over 10 during hydrolysis;(2) the ethanol of 20 per cent to 60 per cent is added and then the strontium chloride aqueous solution with 2times to 2.5times molal weight is directly added, precipitates the crystal, is filtered and dried;(3) water is added to carry out the reflux and the little salt packed in the crude product is removed, and the product is collected through heat filtration.

其特征在于：①将2--3-氰基-4-羧甲基噻吩-5-羧酸四酯在适量氢氧化钠水醇溶液中回流5～6小时，水解过程保持pH值10以上；②然后再加入20-60％乙醇，随后直接加入2-2.5倍摩尔量氯化锶水溶液，析出结晶，过滤，晾干；③加水回流，除去粗品中包裹少量盐，热过滤，收集产品。
