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 bis(tri-t-butylphosphine)palladium (0) (3.0 mg, 0.0058 mmol) and methylzinc chloride (0.087 ml, 0.17 mmol). After stirring for 2 hours, the reaction was loaded directly onto a silica gel column, eluting with hexanes:ethyl acetate (3:1) to yield ethyl 2-(4-(4-((4-chlorophenethyl)carbamoyl)phenoxy)-3-methylphenyl)acetate (20 mg, 76% yield) as a clear oil.
