Process for producing aminophenyl-β-hydroxyethylsulfone |
| abstract |
A process for producing aminophenyl-β-hydroxyethylsulfone of the formula (I), ##STR1## which comprises the following steps: (1) condensing nitrohalobenzene with mercaptoethanol in the presence of an alkali hydroxide and at least one reaction medium selected from N-alkyl-substituted amides and sulfoxides to produce mononitrophenyl-β-hydroxyethylsulfide of the formula (II): ##STR2## (2) oxidizing the mononitrophenyl-β-hydroxyethylsulfide (II) to produce mononitrophenyl-β-hydroxyethylsulfone of the formula (III): ##STR3## and (3) reducing the mononitrophenyl-β-hydroxyethylsulfone to produce the aminophenyl-β-hydroxyethylsulfone of the formula (I). This compound is useful as an intermediate for aminophenyl-β-sulfatoethylsulfone represented by the following formula: ##STR4## which is an important intermediate for vinyl sulfone type reactive dyes largely used for dyeing cellulose fiber materials. |
