Versuchsvorschrift

Ethyl 2-(4-(4-((4-chlorophenethyl)carbamoyl)phenoxy)-3-bromophenyl)acetate (Example 46 step C; 100 mg, 0.193 mmol), 3-(methanesulfonyl)phenylboronic acid (58.1 mg, 0.290 mmol), K2CO3 (80.2 mg, 0.580 mmol) and Pd(PPh3), (22.4 mg, 0.0193 mmol) were diluted with dioxane (2 mL) and water (1 mL). The reaction was purged three times with nitrogen and stirred at 60° C. overnight. The reaction was cooled and loaded directly onto a silica gel column eluting with hexanes:ethyl acetate (2:1) to yield ethyl 2-(6-(4-(4-chlorophenethylcarbamoyl)phenoxy)-3′-(methylsulfonyl)biphenyl-3-yl)acetate (80 mg, 69.8% yield).
