Versuchsvorschrift

Following the general procedure outlined in Synthetic Scheme VI, 5.0 g (16 mmol) of 1-bromo-2-[4-(methylsulfonyl)phenyl]benzene (Step 2) was reacted with 4.1 g (24 mmol) of 3-fluoro-4-methoxyphenylboronic acid (Step 3). Purification by silica gel chromatography (Waters Prep-500A) with ethyl acetate/hexane (35:65) and subsequent recrystallization from ethyl acetate/hexane gave 4.82 g (88%) of 2-fluoro-1-methoxy-4-[2-[4-(methylsulfonyl)phenyl]phenyl]benzene as a colorless solid:
