Electric Literature of 116557-46-1, A common heterocyclic compound, 116557-46-1, name is 3-Bromo-2-methoxyaniline, molecular formula is C7H8BrNO, its 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.
This material (1.8 g) is taken up in methanol (100 ml) containing concentrated hydrochloric acid (0.6 ml), treated with 10% palladium on carbon and hydrogenated at 45 psi for 8 hours. The catalyst is filtered off and the solvent removed at reduced pressure to afford 4-tert-butoxypiperidine hydrochloride.
The synthetic route of 116557-46-1 has been constantly updated, and we look forward to future research findings.
