実験手順
17.7 g of 4-methyl-7-nitro-1H-indazole [Chem. Ber. 37: 2556 (1904)] and 68.0 g of tertbutoxybis(dimethylamino)methane are heated to 80° C. for 45 minutes, combined with diisopropyl ether, suctioned off, and washed with diisopropyl ether, thus producing 22.0 g of N,N-dimethyl-N-[2-(7-nitro-1H-indazol-4-yl)ethenyl]amine, mp 255° C.
後処理
- washwashed with diisopropyl ether
