FIELD: chemistry.SUBSTANCE: invention relates to a method of producing compounds of formulawhere Ra and Rb are selected from H and F and one of Ra and Rb is F, Het is tetrazolyl, optionally substituted with methyl, Ris selected from benzyl and C-Calkyl, optionally substituted with a halogen or C-Calkyloxy. The present method includes combining compoundsandwhere X is selected from Cl, Br, I and trifluoromethanesulphonate, Y is selected from BFand BRR, Rand Rare selected from OH, C-Cmonoalcohols and C-Cdiatomic alcohols, or where Rand Rtogether with B, to which they are attached, form a cyclic boronate optionally substituted with methyl.EFFECT: obtaining oxazolidinones.22 cl, 10 ex, 1 tbl |
