Acetonitrile → 3-(2,4-Dichlorophenyl)-3-oxopropanenitrile

To a stirred solution of acetonitrile (2.0 mL, 38.2 mmol) in THF (50 mL) at −78° C. was added nBuLi (1.81 M in hexane, 16 mL, 28.7 mmol). The resulting slurry was kept at −78° C. for 15 min and 2,4-dichlorobenzoyl chloride (2.0 g, 9.55 mmol) was added dropwise to the acetonitrile anion. After 40 min, the reaction was quenched by addition of saturated NH4Cl (30 mL). THF was removed under reduced pressure and the suspension was filtered. The solid was washed with H2O (100 mL) and dried to give 3-(2,4-dichlorophenyl)-3-oxopropanenitrile (2.0 g, 98%, >95% purity) as a light yellow solid.
