3-substituted acylindole 8a is readily converted into 4-aminopyrazol-3-ylindoles 20, and into 22. Indole reacts with chloroacetyl chloride to yield: 3-chloroacetylindole 9 which could also be utilized for synthesis of a number of 3-substituted indoles.
通过将羧酸与吲哚在乙酸酐溶液中回流得到3-取代的酰化亚环8。形成的3-取代的酰基吲哚8a容易地转化成4-氨基吡唑-3-基吲哚20和22。吲哚与氯乙酰氯反应生成:3-氯乙酰吲哚9,也可用于合成许多3-取代的吲哚。
