YOU Can used Na2CO3 or K2CO3 as catalyst .cyclization phenomena.

thank's

You may be expecting synthesis of 2-aroyl benzofuran or 3-aroyl benzofuran instead 1-aroyl benzofuran as numbering starts from Oxygen as number 1-

Get your nomenclature right, and write after being right! Write in detail too about your problem/query!

Thanks

Hope, you are interested on synthesis of 2-aroyl benzofurans. In such a case you may follow the below article.

Make a condensation with aminophenol in MeOH, EtOH or DMF for 1hour. Juste evaporate the solvent, dilute the crude in dcm and add DDQ, solubilized in dcm too, dropwise. The key is to have a high dilution for the oxydation. This is the best and more efficient way I found to make HBO.
