FIELD: organic chemistry, chemical technology, pharmacy. SUBSTANCE: invention relates to the compound 5-[4- (4-fluorobenzyl)piperidin-1-ylmethyl]-3-(4-hydroxyphenyl)oxazolidine-2-one of the formula (I) 
, its enantiomers and physiologically acceptable salt. Invention relates also to method of synthesis of compound of the formula (I) by interaction of compound of the formula (II) 
where L means Cl, Br and so on with compound of the formula (III) 
and if necessary the synthesized basic compound of the formula (I) is converted to one of its salt by treatment. Invention relates also to pharmaceutical composition eliciting neuroleptic effect containing compound of the formula (I) and/or its physiologically acceptable salt taken in the effective dose and at least one solid, liquid or semiliquid carrier and/or accessory substance. Invention relates also to method for preparing pharmaceutical composition eliciting neuroleptic effect that involves making the dosed form consisting of compound of the formula (I) and/or its physiologically acceptable salts in common with at least one solid, liquid or semiliquid carrier and/or accessory substance. Invention provides the development of novel piperidinylmethyloxazolidinone eliciting neuroleptic effect. EFFECT: improved method for synthesis and preparing, valuable medicinal property of compound. 6 cl, 1 tbl, 11 ex
