실험 절차

A microwave tube was charged with 5-bromo-7-chloro-3-methyl-1H-indazole (610 mg, 2.48 mmol), dioxane (5 mL), Hermann's catalyst (119 mg, 0.12 mmol) and a solution of sodium carbonate (790 mg, 7.46 mmol) in water (10 mL). The mixture was stirred for 20 sec, heated at 165° C. for 30 minutes in a microwave reactor at very high absorption setting. The reaction was vented before handling. The mixture was filtered through diatomaceous earth and washed with EtOAc. The filtrate was concentrated, the residue was dissolved in water and acidified to pH ˜3 with conc HCl. The solids were collected by filtration and dried to afford the title compound (420 mg, 82%).
