Reference of 923590-95-8,Some common heterocyclic compound, 923590-95-8, name is 4-Bromoisoindoline hydrochloride, molecular formula is C8H9BrClN, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

Adding a sodium hydroxide solution to the solution containing Compound I, And extracted with dichloromethane, Add Boc 2 O dropwise, react overnight, add water, separate dichloromethane, wash twice with saturated sodium chloride, dry over anhydrous sodium sulfate, concentrate, separate and purify by column chromatography, use 100-200 mesh silica gel column, wash Deionization using PE (petroleum ether): EA (ethyl acetate) = 40:1-20:1, to give an off-white solid 45g.

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