2-[4-[(BOC-氨基)甲基]苯基]乙酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of methyl 4-(N-BOC-aminomethyl)phenylacetate (9.34 g; 0.033 mol) in THF (100 mL) was stirred under argon at −78° C. and potassium bis(trimethylsilyl)amide (16.7 g, 0.084 mol) in THF (50 mL) was added. After stirring for 30 minutes, 2,4,6-triisopropylbenzene-sulfonyl azide (31.1 g, 0.101 mol) was added as a solid. After 5 minutes, acetic acid (10 mL, 0.175 mol) was added and the reaction warmed to room temperature. The reaction mixture was then partitioned between ethyl acetate (500 mL) and water (500 mL), separated and the organic layer dried (MgSO4). Evaporation of the solvent and purification of the residue by silica gel chromatography afforded the azide (7.1 g, 67%). After 5 minutes The reaction mixture was then partitioned between ethyl acetate (500 mL) and water (500 mL) separated the organic layer dried (MgSO4) Evaporation of the solvent and purification of the residue by silica gel chromatography
