FIELD: chemical engineering.
SUBSTANCE: invention relates to chemical engineering. Described is a set of inventions including the method for producing (S,S) 1,1 bis(4-fluorophenyl)propane-2-yl-2-(3-acetoxy-4-methoxypicolinamido)propanoate (variants) as well as a method for producing complex 2-aminopropanoate ester from 1,1 bis(4-fluorophenyl)propane-1,2-diol (variants). In one variant the method for producing a compound (S,S)-1,1 bis(4-fluorophenyl)propane-2-yl-2-(3-acetoxy-4-methoxypicolinamido)propanote includes binding 4-methoxy-3-acetyloxypicoline acid or 4-methoxy-3-hydroxypicoline acid with a complex 2-aminopropanoate ester obtained from 1,1-bis(4-fluorophenyl)propane-1,2-diol.
EFFECT: invention enables producing 4-alkoxy-3-(acyl or alkyl)oxypicolinamides.
