Abstract
Procedure for preparing furan derivatives, of formula: ** (See formula) ** in which Y means one of the p-chlorophenyl and p-bromophenyl radicals, R1 is chosen from hydrogen and an alkyl radical with 1 to 5 carbon atoms, R2 is one of the methyl and ethyl radicals, as well as a pharmaceutically acceptable salt of said furan derivative, characterized in that when R1 signifies hydrogen a compound of formula is reacted: ** (See formula) ** where Y and R2 have the expressed meanings and R3 is one of the alkyl, benzyl and phenyl radicals, with a strong inorganic base in the presence of water and at an elevated temperature, and then acidifying the reaction mixture and isolating the crude reaction product in a generally known manner to then heat it to 120-150ºC until effervescence ceases.
