YieldReaction ConditionsOperation in experiment
37% With diphenyl phosphoryl azide; triethylamine; In tetrahydrofuran; at 70℃; Step B: Crude 4-Iodosalicylic acid (1.0 g, 3.8 mmol) was dissolved in THF (28 mL) and Et3N (1.15 mL, 8.2 mmol). DPPA (1.7 mL, 7.8 mmol) was added. This was heated at 7O0C overnight. The reaction mixture was then partitioned between H2O and EtOAc. The organic layer was dried and concentrated. Purification by silica gel chromatography (9/1, CH2Cl2/Et0Ac) yielded 472 mg crude intermediate. Trituration with ether yielded 6-iodo-3i7-benzooxazol-2-one (369 mg, 37%) as a white solid.

YieldReaction ConditionsOperation in experiment
44% With copper(l) iodide; trans-N,N'-dimethylcyclohexane-1,2-diamine; sodium iodide; In 1,4-dioxane; at 180℃; for 0.666667h;Microwave irradiation; To a solution of 6-bromobenzo[i/]oxazol-2(3H)-one (0.651 g; 3.04mmol) in 1,4-dioxane (5 mL) was added ?raws-N-N-dimethylcyclohexan-l,2-diamine (0.05 mL; 0.32 mmol), Nal (0.934 g; 6.23 mmol) and then Cul (0.043 g; 0.22mmol). The reaction mixure was heated at 180C under microwave irradiation for 40 min. After cooling, the reaction mixure was diluted in water (15 mL) and EA (20 mL). The aq. layer was extracted three times with EA (3 x 15mL). The evaporation residue was purified by CC (Hept-EA) to afford the title compound (0.352 g; 44% yield) as a reddish solid. 1H NMR (d6-DMSO) δ 11.78 (s, 1H), 7.68 (d, J = 1.5 Hz, 1H), 7.48 (dd, J = 1.5, 8.1 Hz, 1H), 6.92 (d, J = 8.1 Hz, 1H).
