Procedure
Following Example 306b, 307a (422 mg, 1.26 mmol) was converted to the boron intermediate 307b, which was coupled under Suzuki conditions with 109a (420 mg, 1.0 mmol). The crude product was purified via column chromatography: ISCO 24 g silica, 50-100% ethyl acetate/hexanes then 0-10% MeOH, to give 307c (285 mg, 36% yield).
