Procedure

Ethyl 2-(4-(4-((4-chlorophenethyl)carbamoyl)phenoxy)-3-bromophenyl)acetate (Example 46 step C; 30 mg, 0.058 mmol) was diluted with THF (1 mL) followed by the addition of 1,1′-bis(diphenylphosphino)ferrocenedichloropalladium(II) (4.8 mg, 0.0058 mmol) and diethylzinc (0.13 ml, 0.15 mmol). After stirring for 4 hours, the reaction loaded directly onto a silica gel column, eluting with 5-50% ethyl acetate/hexane to yield ethyl 2-(4-(4-((4-chlorophenethyl)carbamoyl)phenoxy)-3-ethylphenyl)acetate (10 mg, 37% yield).
