methyl 2-(2-phenylethylamino)acetate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a stirred solution of 2-phenylethylamine (9.68 g, 40 mmol) in toluene (50 mL) was added methyl bromoacetate (6.12 g, 20 mmol) dropwise at room temperature and was left stirring for 18 hours. The reaction mixture was filtered before removing the solvent in vacuo and the residue was purified by chromatography over silica gel to yield 4.8 g (61%) of the title compound as an oil. NMR (250 MHz, CDCl3) δ(1H, s), 2.92 (4H, m), 3.43 (2H, s), 3.71 (3H, s), 7.27 (5H, m). was left The reaction mixture was filtered before removing the solvent in vacuo the residue was purified by chromatography over silica gel

実験手順: A cold solution (0° C.) of glycine methyl ester hydrochloride (1.0 g, 8 mmol), methanol (25 mL), glacial acetic acid (0.8 mmol, and phenylacetaldehyde (0.481 g, 4 mmol) was treated with sodium triacetoxyborohydride (1.7 g, 8 mmol) in two portions. The reaction mixture was maintained at 0° C. for 1.5 hr, and then quenched with saturated sodium bicarbonate (15 mL). The solution was extracted with ethyl acetate. The organic phase was collected, dried over anhydrous sodium sulfate, and adsorbed onto silica gel (100 mg) and applied to a column prepacked with silica gel. The column was eluted with CH2Cl2/MeOH (97:3, v:v) to afford titled compound (258 mg). quenched with saturated sodium bicarbonate (15 mL) The solution was extracted with ethyl acetate The organic phase was collected dried over anhydrous sodium sulfate The column was eluted with CH2Cl2/MeOH (97:3, v:v)
