Electric Literature of 2398-37-0, A common heterocyclic compound, 2398-37-0, name is 1-Bromo-3-methoxybenzene, molecular formula is C7H7BrO, 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.
The advantageous effect of adding zinc chloride to an amination reaction was demonstrated in the amination reaction of 3-bromoanisole. the results of which are summarized in Table 10. When 3-bromoanisole was reacted under the standard lithium amide amination conditions, using lithium amide (10 eq.) in the presence of (CyPF-^-Bu)PdCl2 (1 mol%) in DME gave a complicated mixture of products was obtained (Table 10, Entry 1). When conducted in the presence of zinc chloride and TMEDA, however, the reaction could successfully gave the desired monoarylation product, 3-methoxyaniline, although at high concentrationsN,N-dimethyl-3-methoxyaniline was formed in a significant amount as a by-
The synthetic route of 2398-37-0 has been constantly updated, and we look forward to future research findings.
