Reaction Steps

The title compound was prepared from N-[1-(2′,4′,5-trifluoro-1,1′-biphenyl-2-yl)ethyl]-3-methoxybenzenesulfonamide (234 mg, 0.55 mmol), anhydrous N,N-dimethylformamide (1 mL), and potassium carbonate (154 mg, 1.1 mmol) according to the procedure and in the same manner as described in Example 105, step d resulting in the isolation of 211 mg (95%) of a white solid. This material was used without further purification in Example 115, step c;
