Procedure
2-Acetyl-1,2,3,4-tetrahydro-benzo[b]thieno[2,3-c]pyridine-3-carboxylic acid ethyl ester and 2-(4-methoxybenzoyl)-1,2,3,4-tetrahydro-benzo[b]thieno[2,3-c]pyridine-3-carboxylic acid ethyl ester were synthesized using 1,2,3,4-tetrahydro-benzo[b]thieno[2,3-c]pyridine-3-carboxylic acid ethyl ester as the starting material by following the same procedure as in Example 5 except that 324 mg of acetic anhydride or 510 mg of 4-methoxybenzoyl chloride, respectively, in place of 614 mg of 2-chlorobenzoyl chloride in Example 5.
