Procedure

Potassium tert-butoxide (8.90 g, 79.3 mmol, 2.20 eq) was added to a stirred solution of 2-(3-chlorophenyl)acetonitrile (4.26 mL, 36.1 mmol) in DMF (50 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 (4.65 mL, 39.7 mmol) was added dropwise via syringe. The reaction mixture was allowed to warm to room temperature and stirred for 20 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 (12.51 g).
