Sodium Iodide → HCID 66679973、化合物

関与物質

反応手順

1.0 g (4.0 mmol) of 5-chloro-2-[(chloroacetyl)amino]benzoic acid, 1.78 g (8.9 mmol) of 4′-fluoro-4-methylbiphenyl-3-amine, and 60 mg (0.4 mmol) of sodium iodide were stirred in 3 mL of DMF at 90° C. for 5.5 hours. Thereafter, the reaction mixture was diluted with ethyl acetate and washed with 1N hydrochloric acid. The organic layer was dried over anhydrous sodium sulfate and the solvent was distilled off under reduced pressure. The obtained crude product was separated and purified by silica gel column chromatography. The separated fractions containing a target compound were combined and condensed. Ethyl acetate was added to the residue, and solids were collected by filtration. The resulting solids were recrystallized using ethyl acetate/n-hexane, thereby giving 334 mg of the target 5-chloro-2-{[N-(4′-fluoro-4-methylbiphenyl-3-yl)glycyl]amino}benzoic acid (yield: 20%).
