Abstract
Process for obtaining heterocyclic compounds of the formula I ** (See formula) ** where R 1 signifies hydrogen or the methyl group, and R 2 an alkyl, aryl or aralkyl radical and X and Y are each chlorine, bromine or iodine, where X and Y may be the same or different, characterized in that the compounds of the formula II ** (See formula) ** where R1, X and Y have the meaning indicated above, they are reacted with an ester of a halogen-formic acid of general formula III HalCOOR2 III where Hal means chlorine or bromine and R2 has the meaning indicated above.
