実験手順
To a solution of 4-bromo-1H-indazole (8.831 g, 44.82 mmol) in DMF (100 mL) was added NaH (60% suspension in mineral oil, 74.7 mmol, 2.988 g) followed by 4-chloro-2-methylsulfanyl-pyrimidine (4.34 mL, 37.35 mmol). The resulting mixture was allowed to stir at RT for 2 h; the solid precipitate was collected by filtration, washed and dried under reduced pressure to give 10.7 g (89% yield) of 4-bromo-1-(2-methylsulfanyl-pyrimidin-4-yl)-1H-indazole.
