Participants

Reaction Steps

To a toluene solution (2.0 mL) of 1-fluoro-4-iodobenzene (62.6 mg, 0.282 mmol), tert-butyl 6,6-difluoro-1,4-diazepane-1-carboxylate (100 mg, 0.423 mmol), cesium carbonate (184 mg, 0.564 mmol), 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (23.3 mg, 0.0423 mmol), and palladium acetate (II) (6.30 mg, 0.0282 mmol) were added and the resultant mixture was stirred under nitrogen atmosphere at 110° C. for 4 hours. After completion of the reaction, the reaction solution was purified by silica gel column chromatography (hexane/ethyl acetate=4/1) to obtain a compound (10.2 mg, yield 11%) in Reference Synthesis Example 260 and a compound (6.30 mg, yield 7%) in Reference Synthesis Example 261 as the title compounds.
