FIELD: chemistry.
SUBSTANCE: method includes reacting an adamantane derivative with an isocyanate derivative in a solvent medium and then extracting the reaction product. The adamantane derivative used is 1,3-dehydroadamantane and the isocyanate derivative is a solution of isocyanic acid solution in diethyl ether prepared in advance. The reaction is carried out while heating to 30-35°C for 3 hours in a medium of diethyl ether with molar ratio of 1,3-dehydroadamantane:isocyanic acid:diethyl ether=1:1.5:20.
EFFECT: method enables to obtain 1-adamantyl isocyanate in mild conditions with high output.
