Abstract

1377296 Substituted 1-amino-naphthalenes FARBWERKE HOECHST AG 24 Aug 1972 [26 Aug 1971] 39508/72 Headings C2C and C2P [Also in Division C4] 1 - Amino - 4 - (# - sulphatoethylsulphonyl)- naphthalene is prepared from the corresponding #-hydroxyethylsulphonyl compound and sulphuric acid at room temperature. 1 - Amino - 4 - (# - phosphatoethylsulphonyl)- naphthalene is prepared similarly using polyphosphoric acid instead of sulphuric acid.
