A process for the preparation of phenylethanolaminotetralins of formula ##STR1## wherein X is hydrogen, a halogen, a trifluoromethyl or a lower alkyl group and R.degree. is hydrogen or a methyl group substituted by a carboxy or a lower carbalkoxy group, which comprises treating a mandelic acid with a 2-amino-7-hydroxytetralin, optionally alkylating with a lower alkyl haloacetate and reducing the amido group of the mandelamide into a methyleneamino group. The mandelamides intermediates are novel.
一种制备式为##STR1##的
苯乙醇胺四氢
萘的过程,其中X是氢、卤素、三
氟甲基或低碳基,R°是氢或被羧基或低碳基卡尔博基基取代的甲基基团,包括将
苯乙酸与2-
氨基-7-羟基四氢
萘处理,可选择用低碳基卤代
乙酸酯进行烷基化,并将苯乙酰胺的酰胺基还原为亚甲基胺基。苯乙酰胺中间体是新颖的。
