Potassium tert-butoxide (4.00 g, 35.6 mmol, 2.20 eq) was added to a stirred solution of 2-(3-(trifluoromethyl)phenyl)acetonitrile (2.53 mL, 16.2 mmol, 1.0 eq) in DMF (30 mL) at 0° C. under a nitrogen atmosphere. The mixture was stirred for 10 minutes at 0° C. before 1-chloro-2-(2-chloroethoxy)ethane (2.09 mL, 17.8 mmol, 1.1 eq) was added dropwise via syringe. The reaction mixture was allowed to warm to room temperature and stirred for 6 hours. The reaction mixture was then cooled to 0° C. and quenched with 10% HCl. The aqueous mixture was extracted with EtOAc (2×). The combined organic layers were washed with brine, dried (MgSO4), and concentrated in vacuo to give the product as an orange oil (6.73 g).
