PROCESS FOR THE PREPARATION OF METHYL N-METHYLANTHRANILATE

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 is feasible towards producing the compound in commercial quantities in high purity and good yield.
