Preparation of 6-methoxyl carbonyl-2-oxo-indoline
-
Paragraph 0009, (2017/05/19)
The invention belongs to the field of pharmaceutical chemistry, and relates to a preparation process of a nintedanib esilate intermediate 6-methoxyl carbonyl-2-oxo-indoline. The process solves the problems of relatively low yield of intermediates and high cost, is convenient for large-scale production, and simultaneously avoids protection of other patents.
