Reaction Steps
Benzothiophene-2-carboxylic acid was treated with 1.5 equivalents of oxalyl chloride in dichloromethane in the presence of a catalytic amount of DMF to form benzothiophene-2-carbonyl chloride. Following procedures described for Example 1 and substituting this acyl chloride for 3-trifluoromethylbenzoyl chloride, compound 77 was prepared in 23% yield.
