4-Chlorophenylboronic acid → HCID 10641092, compound

Participants

Reaction Steps

Following the general procedure outlined in Synthetic Scheme VI, 2.3 g (7.4 mmol) of 1-bromo-2-[4-(methylsulfonyl)phenyl]benzene (Example 4, Step 2) was reacted with 1.7 g (11 mmol) of 4-chlorophenylboronic acid. Purification by silica gel chromatography (Waters Prep-500A) with ethyl acetate/hexane (1:3) and subsequent recrystallization from ethyl acetate/hexane gave 1.90 g (74%) of 1-(4-chlorophenyl)-2-[4-(methylsulfonyl)phenyl]benzene as a colorless solid: mp 180.2°-180.6° C.; NMR (CDCl3) δ 3.06 (s, 3H), 7.04 (d, J=8 Hz, 2H), 7.21 (d, J=8 Hz, 2H), 7.33 (d, J=9 Hz, 2H), 7.38-7.51 (m, 4H), 7.81 (d, J=8 Hz, 2H). MS (EI): m/e (rel intensity) 342 (34), 228 (100); HRMS Calc'd for C19H15ClO2S: 342.0481. Found: 342.0484. Anal. Calc'd for C19H15ClO2S: C, 66.56; H, 4.41; Cl, 10.34. Found: C, 66.45; H, 4.48; Cl, 10.63.
