Reaction Steps

0.26 mmol of 3-Cyano-2-[(1-phenyl-methanoyl)-amino]-4,7-dihydro-5H-thieno[2,3-c]pyridine-6-carboxylic acid 2,2-dimethyl-[1,3]dioxolan-4-ylmethyl ester are dissolved in 10 ml AcCN/H20 (2/1) and 0.1 eq PTSA is added. After stirring over night, some triethylamine is added and the solvent removed. Recrystalization from ethanol gives the desired product in 80% yield.
