1-[(4-氯苯基氨基)甲基]-2-萘酚 | 1-<(4-Chlorphenylamino)methyl>-2-naphthol | 145510-95-8 | C17H14ClNO | 283.757 |
An efficient and environment-friendly method for the synthesis of 1,3-oxazine derivatives has been developed using the ultrasound-mediated condensation of 2-naphthol with formaldehyde and primary amines under solvent-free condition at room temperature in the presence of BF3-SiO2 to give the desired product in good to excellent yield. This procedure provides several advantages over current methods including a simple work-up, cost effectiveness, a reusable catalyst and shorter reaction times.
