Synthetic Route of 13024-17-4,Some common heterocyclic compound, 13024-17-4, name is N-Methyl-3-phenoxyaniline, molecular formula is C13H13NO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: S7 (0.35 g, 2 mmol) was dissolved in Et2O (5 mL) and converted into its hydrochloride salt by drop-wise addition of aq. HCl (1 M) in Et2O. The resulting precipitate was collected byfiltration, dried for 10 min, and used in the subsequent reaction. A mixture of S7 hydrochloride (212 mg, 1 mmol), S1 (185 mg, 1.1 mmol), and toluene (2 mL) was heated to 130 oC,stirred for 21 h, cooled to rt, and diluted with MeOH (5 mL). This solution was concentrated onto silicagel and purified on a silica gel column with gradient elution (EtOAc EtOAc-MeOH;4: 1 v/v). The fractions containing the desired guanidine were collected, concentrated under reduced pressure, andapplied to a second silica gel column eluted with Et3N-EtOAc-hexanes(5: 20: 75 by vol.) to afford 20 asa white solid
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route N-Methyl-3-phenoxyaniline, its application will become more common.
