Product 1

HCID 59654661HCID 59654661, compound

Procedure

Methyl ester (16) (100 mg, 0.30 mmol) was coupled to 3,4-dichloro-phenylboronic acid (61 mg, 0.33 mmol) using Method E. The crude compound was purified by column chromatography, eluting in 17% EtOAc in heptane to give the title compound. Yield: 33 mg, 27%; LC/MS tr 1.70 min; MS(ES+) m/z 404, 406 (M+H)
