FIELD: organic chemistry. SUBSTANCE: method involves dehydration of phenyl- or 4-bromophenyl pyroracemic acid. The process is carried out at room temperature with the help of trifluoroacetic anhydride in the medium of inert organic solvent. Desired products have essential formulae C10H6O3, and C10H5BrO3, their decomposition point being 136-137 C and 145-146 C respectively. Yield of said products is 92 % and 84 % respectively. EFFECT: creates novel method for production of novel compounds.
