Participants

Reaction Steps

The title compound was prepared from 4-methoxybenzenesulfonyl chloride (146 mg, 0.7 mmol), 1-(-2′,4′,5-trifluoro-1,1′-biphenyl-2-yl)ethylamine (169 mg, 0.67 mmol), and triethylamine (187 μL, 1.3 mmol) according to the procedure and in the same manner as described in Example 105, step c. The product was purified by preparative liquid chromatography on a Biotage® 40 Mi column of prepacked silica gel (90 g), eluting with a gradient of 30%-50% methyl tert-butyl ether in hexane (35 min), to afford the desired compound (197 mg, 70%) as a white solid;
