Abstract

PURPOSE: Specific amounts of formaldehyde and formic acid are made to act on α-amino-ε-caprolactam to convert selectively only the amino group to dimethyl derivative, thereby giving title compound under mild conditions in high yield.
CONSTITUTION: To one mole of α-amino-ε-caprolactam are added no more than 8, preferably 2W5 moles of formaldehyde and no more than 12, preferably 2W7.5 moles of formic acid and the mixture is heated to 50W100°C to form α-dimethylamino-ε-caprolactam. Formaldehyde can be used in the form of either an qqueous solution or an oligomer such as paraformaldehyde.
