Reaction Steps

A stirred suspension of 4-methoxy-N-[1-(2′,4,4′-trifluoro-1,1′-biphenyl-2-yl)ethyl]benzenesulfonamide (0.74 g, 1.74 mmol) and potassium carbonate (0.48 g, 3.50 mmol) in N,N-dimethylformamide (5 mL) was heated for twelve hours at 100° C. The reaction mixture was cooled and poured into distilled water. After stirring overnight at room temperature, a precipitate was filtered and dried under high vacuum. The precipitate was purified by preparative liquid chromatography on a Biotage® 40 Mi column of pre-packed silica gel (90 g), eluting with a mixture of 15% methyl tert-butyl ether in hexane at a flow rate of 50 mL/min to afford, after evaporation of the solvent, a colorless solid. Crystallization from diethyl ether-hexane yielded the title compound (0.67 g, 1.65 mmol, 95%) as a homogeneous, colorless, crystalline solid, m.p. 141-143° C.;
