With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4442-53-9,2,3-Dihydrobenzo[b][1,4]dioxine-5-carboxylic acid,as a common compound, the synthetic route is as follows.
Example 99a(S)-ethyl 4-amino-5-(2-(2,3-dihydrobenzo[b][1,4]dioxine-5-carboxamido)-butoxy)-2-methylquinoline-3-carboxylatePrepared as in Example 24a from (S)-ethyl 4-amino-5-(2-aminobutoxy)-2-methylquinoline-3-carboxylate (Example 97b) and 2,3-dihydrobenzo[b][1,4]dioxine-5-carboxylic acid as brown solid (40percent). MS 480 (MH+).
The synthetic route of 4442-53-9 has been constantly updated, and we look forward to future research findings.
