71.7% | With bis-triphenylphosphine-palladium(II) chloride; potassium carbonate In toluene at 90 - 100℃; for 24 h; Inert atmosphere | 13.3 g of compound iii (0.062 mol), 12.1 g of compound vi (0.075 mol), 4.5 g of bis(triphenylphosphine)palladium(II) chloride (0.006 mol), 1.0 mol/L potassium carbonate solution 64ml in argon under the protection of added to 133ml toluene, heated to 90 ~ 100 , incubation reaction 24h. The reaction mixture was poured into 200 ml of purified water, extracted with 70 ml of ethyl acetate three times, twice with 100 ml of saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give a pale gray solid which was beaten with petroleum ether for 1 hour to give an off-white solid, i.e., Oprinon (compound ii), and weighed 11.2 g in a yield of 71.7percent. |

72% | With tris-(dibenzylideneacetone)dipalladium(0); sodium acetate; tricyclohexylphosphine In 1,4-dioxane at 115 - 120℃; for 24 h; | 20.0 g of compound vii (0.102 mol), 38.7 g of bis(pinacolato)diboron (0.152 mol), 2.85 g of tricyclohexyl phosphine (0.010 mol), 4.65 g of tris(dibenzylideneacetone)dipalladium (0.005 mol) and 25.0 sodium acetate were added to 200ml 1,4-dioxane, heated to 115 ~ 120 , incubation reaction 24h, cooling to room temperature, adding purified water 200ml. Extracted twice with 200 ml of ethyl acetate, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give a reddish brown solid. The solid was added to 30 ml of t-butyl methyl ether, stirred for 2 h. A yellowish solid, i.e. 9-azoindole-5-boronic acid (compound vi), was filtered off and weighed 11.8 g in a yield of 72.0percent. |
