Step AAN (1): 2-(4-Ethoxyphenyl)acetic acid (2.00 g, 11.1 mmol) was deprotonated with NaHMDS 2.0 M in THF (12.5 mL, 25.0 mmol) and reacted with 1-chloro-4-iodobutane (1.49 mL, 12.2 mmol) using a procedure analogous to Step AC (1) and after silica gel column chromatography (30-80% EtOAc/hexanes) afforded 6-chloro-2-(4-ethoxyphenyl)hexanoic acid (1.10 g, 4.06 mmol, 37% yield) as a pale-yellow oil. LC-MS (M+Na)+ 293.1.
