A solution of 62 mg 2-phenoxyethylamine and 12 mg N,N-diethylsalicylaminde in 0.5 ml of dry DMF was then added via septum. Under inert conditions the reaction mixture was heated to 1000C for 20 h. It was then diluted with ethyl acetate and water, the pH was adjusted to neutral, the layers were separated and the aqueous layer was extracted with ethyl acetate twice. The combined organic layers were dried over magnesium sulphate and evaporated. After purification by RP-HPLC 12 mg 2-methyl-2-{[1-(2-phenoxy- ethylamino)-naphthalene-2-carbonyl]-amino}-propionic acid were obtained.C23H24N2O4 (392.46), LCMS (ESI): 393.16 (MH+).

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 1758-46-9, name is 2-Phenoxyethylamine, A new synthetic method of this compound is introduced below., HPLC of Formula: C8H11NO

[0070] [6-CHLORO-N- (2-METHOXYBENZYL)-NAPOS;- (2-PHENOXYETHYL)- [1,] 3, 5] triazine- 2, 4-diamine (3). Procedure 1 : 1.00 eq. of 2 in [CH2C12] is cooled to ODC under nitrogen and Et3N or Hunig’s base (3.00 eq. ) is added. To the stirring solution, 1.00 eq. [OF 2-PHENOXY-ETHYLAMINE] is added dropwise. The temperature rises several degrees upon completion of addition ; warming is then allowed to continue until the reaction reaches room temperature. The reaction is allowed to stir at room temperature for 12 hours and then the mixture is partitioned between [CHUCK] and 1.0 N [HC1.] The acid layer is extracted once with [CH2C12] and then the pooled [CH2C12] layers washed several times with H20 and once with brine. The [CH2CI2] extract is dried over [NA2S04,] and the solvent removed under reduced pressure to provide crude 3, which is purified by flash chromatography using 1: 4 ethyl acetate (EtOAc)/hexanes as eluent. [0071] Procedure 2: 1.00 eq. of 2 in CH2C12 is cooled to [OOG] under nitrogen and Et3N or Hunig’s base (3.00 eq. ) is added. To the stirring solution, 1.00 eq. of 2- [PHENOXY-ETHYLAMINE] is added dropwise. The temperature rises several degrees upon completion of addition; warming is then allowed to continue until the reaction reaches room temperature. The resulting mixture is heated to [100¡ãC] for 30 minutes, cooled to room temperature, and partitioned between [H20/CH2C12.] The aqueous layer is extracted with [CH2C12] and combined organic extracts were dried over [NA2S04.] The solvent is removed under reduced pressure and the resulting residue is purified by flash chromatography [(1] : 4 EtOAc/hexanes) to yield 3.
