Abstract

Compounds of the formula are prepared by heating with water at 0-100 DEG C. compounds of formula which are in turn prepared by reacting with H2N-R11 hydrohalide at 70-160 DEG C. in an inert solvent. R1 and R11 are aliphatic, cycloaliphatic, aromatic, condensed aromatic or heterocyclic radicals optionally substituted by halogen and/or alkyl, nitro, dialkylamino, alkoxy or alkylmercapto radicals, or are dialkylamino radicals and n is 1, 2 or 3.
