1-Bromo-2-Chloroethane → HCID 4493084, compound

Participants

Reaction Steps

A 1 L round-bottomed flask was charged 2-hydroxyisoindoline-1,3-dione (16.6 g, 98.71 mmol), followed by DMF (100 mL), then 1-bromo-2-chloroethane (25.2 mL, 296.1 mmol), and then triethylamine (42.1 mL, 296.1 mmol). After stirring at ambient temperature overnight, the reaction mixture was filtered (GF/F) and rinsed with DMF. The filtrate (250 mL) was poured into ice-water (2 L) while stirring, and the resulting precipitate was filtered, rinsed with water, and dried, yielding the crude product as a white solid (21 g). The crude product was triturated with heptane (3×400 mL), filtered and air-dried, giving the product as white solid (17.6 g, 79%).
