| titleOfInvention | Process for preparing 3-(4-aminoethoxy-benzoyl)benzo¬b|- thiophenes |
| abstract | The invention provides a process for preparing 6-alkoxy-3-(4-alkoxyphenyl)benzo[B]thiophenes in good yield on a manufacturing scale without generating a thick, potentially yield-reducing, paste. The invention also provides methods for converting a-(-alkoxyphenylthio) -4-alkoxyacetophenones into 6-hydroxy-2-(4-hydroxyphenyl)-3-[4-(2-aminoethoxy)-benzoyl]benzo[B]thiophenes via acylation of a dialkoxy benzo[B]thiophene. Each of these preparations relies on an intramolecular cyclization of a dialkoxy acetophenone derivative to yield a benzo[B]thiophene without generating a thick paste that lowers overall yields on a manufacturing scale. |
