Procedure
Step AL (1): 2-(3,5-Difluorophenyl)acetic acid (2.5 g, 14.5 mmol) was deprotonated with NaHMDS (1.0 M in THF, 29.0 mL, 29.0 mmol) and reacted with 1-chloro-4-iodobutane (1.78 mL, 14.5 mmol) using a procedure analogous to Step AC (1) to afford 6-chloro-2-(3,5-difluorophenyl)hexanoic acid (3.25 g, 85% yield). LC-MS (m-H)− 261.1. The crude product was used for subsequent chemistry without purification.
