Recommanded Product: 923590-95-8

A solution of 4-bromoisoindoline hydrochloride (8.00 g, 34.33 mmol) in dichloromethane (20 mL) and triethylamine (14.3 mL, 103.0 mmol) was cooled to 0 C, and then di-tert-butyl dicarbonate (15.0 g, 68.73 mmol) was added. The mixture stirred overnight at room temperature and was then quenched by the addition of 50 mL of water. The resulting solution was extracted with 3×50 mL of dichloromethane, washed with 1×50 mL of brine, dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum. The residue was purified via column chromatography on silica gel (eluting with ethyl acetate/petroleum ether (1 :5)) to afford tert-butyl 4-bromoisoindoline-2-carboxylate (9 g, 75%) as a white solid. MS: (ESI, m/z): 242 [M-t-Bu+H]+

The synthetic route of 923590-95-8 has been constantly updated, and we look forward to future research findings.
