| titleOfInvention | Alkyl esters of 4-C-3-halo-2-hydroxy-pro-alkoxy-phenylcarbonic acid and the methods for their preparation |
| abstract | The solution relates to 4-C / 3- alkyl estersn-halogen-2-hydroxy / -propoxy-3-phenylcarbanic;nacids of formula i,nwherein R is straight chain alkyl of 1 to 5 atomsncarbon, branched alkyl of 3 to 4ncarbon atom, alkenyl having 2 to 3 atomic atomsncarbon, cycloalkyl having 5 to 7 carbon atomsnand X is halogen. The compounds arencan be prepared by reactingn4-hydroxyphenylacartamic acid alkyl esternwith 3-halo-1,2-epoxypropenenunder basic catalysis of piperidine du-.nsalified compounds or alkyl acid estersn4- [72,3-epoxy / propoxy] phenylcarbamic acidnwith halogic acidnin an aqueous solution of ethyl methyl ketone ornacetone. The solution falls within the organic fieldnSynthesis. |
