Acetyl chloride → 1-(6-Nitroindolin-1-yl)ethanone

関与物質

反応手順

6-Nitroindoline (3.0 g, 18.3 mmol) is dissolved in THF (45 mL) and Et3N (3.4 mL, 24.4 mmol) at 0° C. Acetyl chloride (1.5 mL, 21 mmol) is added dropwise. The mixture is stirred at room temperature for 30 minutes. The mixture is partitioned between EtOAc and aqueous HCl. The organic layer is dried and concentrated to yield 1-acetyl-6-nitroindoline (3.8 g, 100%) as a yellow solid.
