摘要：
A mixture of methyl anthranilate, dissolved in a water-miscible solvent, with a solution of formaldehyde is reduced in a hydrogen atmosphere in the presence of a hyrogenation catalyst at moderate temperatures and pressures to yield methyl N-methylanthranilate. The invention provides a process which can produce the compound in commercial quantities in high purity and good yield.
