Title: Improved production of 3-(4-aminoethoxybenzoyl)benzo(b) thiophene
Inventor: CHIYAARUZU AASAA ARUTO
IPC: C07B61/00
Filed: 1995-07-20
Abstract: The invention provides a process for preparing 6-alkoxy-3-(4-alkoxyphenyl)benzoÄBÜthiophenes 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-Ä4-(2-aminoethoxy)-benzoylÜbenzoÄBÜthi ophenes via acylation of a dialkoxy benzoÄBÜthiophene. Each of these preparations relies on an intramolecular cyclization of a dialkoxy acetophenone derivative to yield a benzoÄBÜthiophene without generating a thick paste that lowers overall yields on a manufacturing scale.
