실험 절차

Step AH (1): 2-(4-Chlorophenyl)acetic acid (2.5 g, 14.65 mmol) was deprotonated with NaHMDS (1.0 M in THF, 29.3 mL, 29.3 mmol) and reacted with 1-chloro-4-iodobutane (1.80 mL, 14.7 mmol) using a procedure analogous to Step AC (1) to afford 6-chloro-2-(4-chlorophenyl)hexanoic acid (3.47 g, 59% yield). LC-MS (M−H)− 259.1.
