PURPOSE:To readily obtain the subject compound having amino group at meta- position from raw material of a low cost in high yield by reacting 3-amino-alpha- methylbenzyl alcohol with phenols in the presence of acid catalyst. CONSTITUTION:3-amino-alpha-methylbenzyl alcohol is reacted with phenols (e.g., phenol, cresol or xylenol) expressed by formula I (R<1> and R<2> are H, 1-9C alkyl, cycloalkyl, aryl or aralkyl; n is 1 or 2) in the presence of an acid catalyst to afford 1-(3-aminophenyl)-1-(hydroxyphenyl) ethane derivative [e.g., 1-(3- aminophenyl)-1-(4-hydroxy-3,5-dimethylphenyl) ethane]. Said product is useful as a raw material of heat-resistant resin and said resin is bearable to instantaneous impact such as stress concentration. |
