Procedure
The title compound was synthesized from 3-(4-methoxyphenyl)cyclopentanone (INTERMEDIATE 75, Step B) and commercially available starting materials using an analogous method to that described for INTERMEDIATE 7. Bis(neopentyl glycolato)diboron was used instead of BISPIN to afford a mixture of the titled compound and methyl (1S,3R)-3-[3-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-4-methoxyphenyl]cyclopentanecarboxylate. The mixture was used without further purification.
