Abstract

Process for the manufacture of halogenated compounds of the pregnane series of general formula i ** (see formula) ** Wherein x means a halogen atom, especially chlorine, fluorine or bromine and r means an alkyl radical having 1 to 5 carbon atoms, from corresponding derivatives of 17alpha-acyloxy-3-alkoxy-6-halogen-16-methylene -pregna-3,5-diene-20-one of the general formula ii ** (see formula) ** Wherein x and r mean the same as in formula i and r'means an alkyl radical having 1 to 6 carbon atoms, characterized in that it is transformed to the starting compound by the addition of 1 mol of halogen in elemental form or 1 mol of a hypohalogenous acid, with simultaneous spontaneous hydrolysis of the alkoxy group in position 3, in the corresponding derivative 6alpha, 6beta-dihalogeno-17alpha-acyloxy-16-methyleneprogesterone of the general formula iii ** (see formula) ** Wherein x and r mean the same as in formula i, and y means a halogen atom, especially chlorine or bromine, which is identical to or may be different from the halogen atom x, after which it is separated from it the hydrogen halide hy is derived, with formation of the compound of the general formula i.
