Procedure
Referring to Scheme 4, methoxybenzothiophene ester 1, for example, is converted to the corresponding hydroxybenzothiophene carboxylic acid 2 with boron tribromide. Carboxylic acid 2 is coupled with Hca amine to yield hydroxybenzothiophene amide 3. 1-Substituted 4-hydroxypiperidine 4 is coupled with amide 3 to yield (piperidin-4-yloxy)benzothiopheneamide 5.
