27492-84-8, name is Methyl 4-amino-2-methoxybenzoate, belongs to esters-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Safety of Methyl 4-amino-2-methoxybenzoate
(2) the above-mentioned the resulting 4-amino-2-methoxybenzoic acid methyl ester and N-chloro succinimide the mole ratio is that 1:1 in 70 C stirring in DMF solution of 3 hours later, is poured into the ice water is separated out in solid, filtering and drying to obtain 1.70 kg of 4-amino-5-chloro-2-methoxybenzoic acid methyl ester, in the yield of 88.3%.
The synthetic route of 27492-84-8 has been constantly updated, and we look forward to future research findings.
