Arylamino-thieno-oxobutanainides under Lawesson's conditions: Competition between thienylpyrrole and bithiophene formation

1-Aryl-2-thienyl-substituted pyrroles and/or 5-arylamino-2,2′- bithiophenes were synthesized by treatment of arylamino-thieno-oxobutanamides with Lawesson's reagent. These in turn were prepared by direct amidation of 4-oxo-(2-thienyl)butanoic acid through DCC-BtOH mediated reactions.
