Thionyl chloride (20 mL, 0.274 mol) and N,N-dimethylformamide (2 mL) are added to a stirred solution of 4-[5-(2-fluorobiphenyl-4-yl)-1,2,4-oxadiazole-3-yl]phenylmethanol (32 g, 0.092 mol) in dichloromethane (150 mL) at 0° C. The reaction mixture is heated at 80° C. for 1 hour and then concentrated under reduced pressure. The residue is neutralized with a saturated aqueous sodium bicarbonate solution (150 mL) to furnish a solid which is filtered and washed with n-hexane (150 mL) to give 3-(4-chloromethylphenyl)-5-(2-fluorobiphenyl-4-yl)-1,2,4-oxadiazole.
