Chemistry is traditionally divided into organic and inorganic chemistry. category: Isoquinolines, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 394-67-2
The invention belongs to the field of medical technology, and in particular relates to the treatment of ocular hypertension of pharmaceutical intermediates preparation method, the invention provides a high selective sulfonation 4 – […] quinoline preparation 4 – […] quinoline – 5 – sulfonic acid, the heteropoly acid as an additive in the 4 – quinoline […] sulfonation reaction time, improves the 4 – quinoline […] conversion, and has reduced the 8 bit sulfonation proportion of the by-product, compared with the prior art, significantly improving the selectivity of the target product.
