With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.262368-30-9,N-(4-Aminophenyl)-N-methyl-2-(4-methylpiperazin-1-yl)acetamide,as a common compound, the synthetic route is as follows.
262368-30-9, A 500ml reaction flask was charged 30g of compound V, 22.5g compound of the VI, ethanol 300ml, sodium bicarbonate and 15g, the reaction was heated to reflux for 2 hours, the reaction mixture was added to 600ml of water, there are large amount of solid precipitated, was filtered, the cake washed with 100ml washed once with methanol, a yellow solid 41.9g nintedanib (I) .Yield 92.7%.
The synthetic route of 262368-30-9 has been constantly updated, and we look forward to future research findings.
