Participants

Reaction Steps

A mixture of Example 11B (29.8 mg, 0.071 mmol), 4-chlorophenylboronic acid (45 mg, 0.288 mmol), Cu(OAc)2 (24 mg, 0.132 mmol), Et3N (45 μL, 0.324 mmol), pyridine (60 μL, 0.743 mmol), and dichloroethane (1 mL) was heated at 75° C. for 1.5 h. Concentration in vacuo followed by flash chromatography (50% to 100% EtOAc/Hexanes) to yield a Example 11C which was further purified by recrystallization fom MeOH to give 23 mg (61%) of a solid.
