With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.10338-57-5,4-(Piperidin-1-yl)benzaldehyde,as a common compound, the synthetic route is as follows.
Route 2: 1.94g of 4-methoxy-2-methylquinoline and 1.89g of 4-(piperidin-1-yl)benzaldehyde were added to a 250ml round bottom flask with a spherical condenser.The mixture was heated in an oil bath on an Ika magnetic stirrer, and 1.88 g of p-toluenesulfonamide was added as a catalyst, and 8 ml of toluene was used as a solvent, and the mixture was heated under reflux for 72 hours.The solvent was sparged and recrystallized from 2 ml of ethanol to give a pale yellow solid.The yield was 94%.
10338-57-5, 10338-57-5 4-(Piperidin-1-yl)benzaldehyde 291354, apiperidines compound, is more and more widely used in various fields.
