| Reactant | 4-(Methylthio)phenylboronic acid | HCID 2733959 | — |
| Reactant | 3-Chloro-4-fluorophenylboronic Acid (contains varying amounts of Anhydride) | HCID 2734660 | — |
| Product | 1-(3-Chloro-4-fluorophenyl)-4,5-difluoro-2-[4-(methylthio)phenyl]benzene | HCID 23451322 | 64% |
Reaction Steps
Following the general procedure outlined in Synthetic Scheme VII, 4.1 g (15 mmol) of 1,2-dibromo-4,5-difluorobenzene, 3.0 g (18 mmol) of 4-methylthiophenylboronic acid (Example 1, Step 2) and 2.9 g (16.5 mmol) of 3-chloro-4-fluorophenylboronic acid were reacted. Purification by silica gel chromatography gave 3.5 g of 1-(3-chloro-4-fluorophenyl)-4,5-difluoro-2-[4-(methylthio)phenyl]benzene as a semi-solid which was used without further purification.
