The manufacturing synthesis of 5-hydroxy-2-methyl-1H-indole is described and two synthetic methods were used and the results discussed. Two small and three large runs with Nenitzescu’s method were analyzed and results reported with different reaction conditions. Manufacturing issues encountered were discussed. Production scale of more than 60 kg of the 5-hydroxy-2-methyl-1H-indole-3-carboxylic acid ethyl ester and over 20 kg of the 5-hydroxy-2-methyl-1H-indole were achieved. Based on these results, larger scale manufacturing of this product or similar products based on the optimized conditions is feasible.
介绍了 5-羟基-2-甲基-1H-吲哚的制造合成,使用了两种合成方法并讨论了结果。分析了使用 Nenitzescu 方法进行的两次小规模和三次大规模运行,并报告了不同反应条件下的结果。讨论了生产过程中遇到的问题。5-hydroxy-2-methyl-1H-indole-3-carboxylic acid ethyl ester 的生产规模超过 60 kg,5-hydroxy-2-methyl-1H-indole 的生产规模超过 20 kg。基于这些结果,在优化条件下大规模生产该产品或类似产品是可行的。
