the application concerns a (2e) - 2 - [(1r, 4r, 6s) - 4,7,7trimetylobicyklo [4.1.0] hept-2-en - 3 - ylidene) ethanol of formula 1. the declaration also contains a process for the production of (2e) - 2 - [(1r, 4r, 6s) - 4,7,7trimetylobicyklo [4.1.0] hept-2-en - 3 - ylidene) ethanol, which is characterised by the fact that (2e) - 2 - [(1r, 4r, 6s) - 4,7,7trimetylobicyklo [4.1.0] hept-2-en - 3 - ylidene] acetate is subjected to reduction reaction.with the reaction is carried out in an ice bath using glinowodorek lithium as reducer and tetrahydrofuran as a solvent, and after completion of the reaction bearing glinowodorku lithium reducing with water, and subsequently the mixture poreakcyjnu0105 is extracted with diethyl ether, drought s if anhydrous magnesium sulphate and draining, after which the vaporized solvents.and the crude product is purified by using column chromatography.
