FIELD: chemistry.
SUBSTANCE: method consists in reacting 4-fluoroacetophenone with an acetylenic compound in the presence of solvents. The acetylene compound is gaseous acetylene and, as a solvent, dimethylsulfoxide containing 0.1-0.5% of water, the process is carried out in the presence of a catalytic system, which is prepared by preheating hydrated potassium hydroxide, diethylene glycol and dimethylsulfoxide at a molar ratio of 4-fluoroacetophenone: KOH×0.5H2O: diethylene glycol of 1:0.25-1.0:0.5-1.0, at the temperature of 100-120°C for 0.5-1.0 h, the main reaction is carried out at the temperature of 10-20°C for 1-4 hours, and the desired product is isolated by extraction with diethyl ether, followed by distillation in vacuum.
EFFECT: obtaining the target alcohol with a yield of 91 percent.
