Procedure
3-Cyano-2-[3-(2-methoxy-phenyl)-propionylamino]-4,7-dihydro-5H-thieno[2,3-c]pyridine-6-carboxylic acid 2-acetoxy-ethyl ester (Example 31) is stirred in 1N NaOH over night at room temperature. After acidification with aqueous HCl the precipitated product is filtered off and recristalized from ethanol.
