FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing N-(3,3-dimethyl-3,4-dihydroisoquinolyl-1)-6-aminocaproic acid, which includes reacting 1-methylthio-3,3-dimethyl-3,4-dihydroisoquinoline with ε-aminocaproic acid while heating in an autoclave without a solvent, followed by purification of the product by crystallisation from water.
EFFECT: method significantly increases the output of the end product, cuts the duration of the process, reduces the risk of fire and material costs owing to use of water for recrystallisation.
