用途と製造
応用分野
用途有機合成原料。
使用4-Hydroxyindole is a Pindolol (P468000) impurity, which is a mixed adrenergic blocker and serotonin 5HT1A-receptor antagonist.
一般的な説明Glucouridination of 4-hydroxyindole by human uridine 5′-diphospho-glucuronosyltransferase has been repotrted.
調製方法
製造方法Synthesis of 4-hydroxyindole: Using resorcinol as raw material, 4-oxotetrahydrocoumarone carboxylic acid is prepared by isomerization, catalytic hydrogenation, and cyclization with ethyl bromopyruvate. It was added to methanol solution saturated with ammonia, and the reaction was heated in an autoclave to generate 4-oxotetrahydroindole. Finally, 4-hydroxyindole is obtained by dehydrogenation and isomerization.
