FIELD: chemistry.
SUBSTANCE: present invention relates to a method for producing 5,7-dimethyl-3-hydroxymethyl-1-adamantanol, which can be used as a starting substrate in the synthesis of esters - the key components of the basic bodies of oils for heat-stressed gas turbine engines of modern aviation. This method consists in the interaction of 5,7-dimethyl-3-hydroxy-1-adamantancarboxylic acid with ethyl chloroformate in a molar ratio of 1:1–2 based on the initial substrate in the presence of triethylamine in THF at room temperature for 2–6 h followed by filtration of triethylamine hydrochloride and the addition of sodium borohydride in a molar ratio of 1:2–4, based on the initial substrate.
EFFECT: proposed method allows to obtain the target product with a high yield using simple technology.
