5-cyanobenzofuran-2-carboxylic Acid → HCID 18919426, compound

Participants

Reaction Steps

In the same manner as in Example 75 (2), 5-cyano-2-benzofurancarboxylic acid (1.00 g, 5.34 mmol) was converted a corresponding acid chloride and reacted with ethyl 3-(4-hydroxypiperidino)propionate (1.08 g, 5.77 mmol). The reaction mixture was purified by silica gel column chromatography (chloroform) to give 733 mg of ethyl 3-[4-[(5-cyano-2-benzofuranyl)carbonyloxy]piperidino]propionate as a colorless solid (33%).
