反应条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Into a 250-mL 4-necked round-bottom flask, was placed 4-(2,6-difluorophenoxy)-aniline (8.84 g, 39.96 mmol, 1.00 equiv), hydrogen chloride (37%) (10.14 g, 277.81 mmol, 6.95 equiv) and water (20 mL). NaNO2 (3.04 g, 44.06 mmol, 1.10 equiv) in water (10 mL) was added dropwise with stirring at 0° C. over 5 min., and the reaction mixture was stirred for 30 mins at 0° C. The reaction mixture was added into a solution of NaI (18 g, 120.00 mmol, 3.00 equiv) in water (20 mL) at 25° C. in batches over 5 min. The resulting solution was stirred for 2 h at 25° C. and then extracted with of ethyl acetate and the organic layers were combined. The combined organic layers were washed with water and brine, dried over anhydrous sodium sulfate and concentrated under vacuum to give 10.2 g (77%) of 1,3-difluoro-2-(4-iodophenoxy)benzene as brown oil. Into a 250-mL 4-necked round-bottom flask, was placed the reaction mixture was stirred for 30 mins at 0° C The resulting solution was stirred for 2 h at 25° C. extracted with of ethyl acetate The combined organic layers were washed with water and brine dried over anhydrous sodium sulfate concentrated under vacuum
