A novel process for the preparation of 7-acylindolin-2-ones of the formula: ##STR1## wherein R is hydrogen, halogen, lower alkyl, lower alkoxy, or trifluoromethyl; R.sup.1 is lower alkyl, alkylphenyl, cycloalkyl, or aryl; and R.sup.2 is hydrogen, lower alkyl or benzyl is provided. The compounds are useful as intermediates in the preparation of 2-amino-3-acylphenylacetic acid compounds which possess pharmaceutical properties.
一种制备式为:##STR1## 其中R为氢、卤素、低碳基、低烷氧基或三
氟甲基;R.sup.1为低碳基、烷基苯基、环烷基或芳基;R.sup.2为氢、低碳基或苄基的7-酰基
吲哚-2-酮的新工艺被提供。这些化合物可用作制备具有药物性质的2-
氨基-3-酰基苯基
乙酸化合物的中间体。
