Reaction Conditions

Reaction Steps

LiHMDS (1.06 M in THF, 1.32 mL, 1.40 mmol) was added to a solution of 2-fluoro-4-(oxazol-5-yl)benzonitrile 38 (0.22 g, 1.17 mmol) in THF (20 mL) at −78° C., and the mixture was stirred at −78° C. for 1 h. A solution of hexachloroethane (0.415 g, 1.75 mmol) in THF (5 mL) was added at −78° C., and the mixture was stirred at −78° C. for 2 h and allowed to warm to room temperature and stirred for 14 h. The reaction was quenched by adding EtOAC: H2O (50 mL: 15 mL), and then extracted with Ethyl acetate. The extracts were washed with brine, dried (Na2SO4) and concentrated. The product was purified by column chromatography (Acetone/hexane as an eluent) to provide 4-(2-chlorooxazol-5-yl)-2-fluorobenzonitrile 39 (0.18 g, 70% yield) as white solid. MS (ES) m/z 223 (M+H+).
