Procedure
Following the general procedure outlined in Synthetic Scheme IV, 33 g (140 mmol) of 1,2-dibromobenzene was reacted with 12 g (70 mmol) of 4-methylthiophenylboronic acid (Example 1, Step 2). Purification by silica gel chromatography with hexane gave 17.2 g (89%) of 1-bromo-2-[4-(methylthio)phenyl]benzene as a colorless oil: NMR (CDCl3) δ 2.53 (s, 3H), 7.16-7.23 (m, 1H), 7.28-7.39 (m, 6H), 7.66 (d, J=8 Hz, 1H).
