Reaction Steps

Step AK (1): 2-(4-Chloro-1H-pyrazol-1-yl)acetic acid (2.5 g, 15.57 mmol) was deprotonated with NaHMDS (1.0 M in THF, 31.0 mL, 31.0 mmol) and reacted with 1-chloro-4-iodobutane (1.91 mL, 15.6 mmol) using a procedure analogous to Step AC (1) to afford, after silica gel column chromatography (10-75% EtOAc/heanes), 6-chloro-2-(4-chloro-1H-pyrazol-1-yl)hexanoic acid (2.2 g, 56% yield). LC-MS (M−H)− 249.1.
