実験手順
To a solution of 5,6-dichloroisatin (0,15 g; 0.7 mmol) in anhydrous DMF (5 ml) was added sodium hydride (40 mg, 60% dispersion in mineral oil). When the evolution of hydrogen had ceased iodomethane (0.1 ml) was added and the mixture was stirred for 20 min. at ambient temperature. Water (15 ml) and glacial acetic acid (0.1 ml) were added and the product was filtered off, washed with water and dried to yield 5,6-dichloro-1-methylisatin (0.13 g, 81%). The following compounds were prepared analogously: 4,5-dichloro-1-methylisatin (2b) from 4,5-dichloroisatin, and 6,7-dichloro-1-methylisatin from 6,7-dichloroisatin.
