PROCEDURE
实验过程
4-Chloro-3-[5-chloro-1-(2,4-dimethoxybenzyl)-3-methyl-2-oxoindolin-3-yl]benzoic acid, in the racemic form, is treated with N-ethyl-3-pyridylmethylamine (document WO 01/074775, example 201a) and b)). 4-Chloro-3-[5-chloro-1-(2,4-dimethoxybenzyl)-3-methyl-2-oxoindolin-3-yl]benzoic acid, in the racemic form, is described in the document WO 01/074775, in example 101. After silica chromatography, elution being carried out with a dichloromethane/methanol 90/10 mixture, the expected compound, in the racemic form, is obtained crystallized from methanol (white powder).
