The reaction of phenylethylamine (1) with methyl acrylate (2), performed in two steps, led to N-(P-carbomethoxyethy1)phenethylamine (3) and N,N-bis-(P-carbomethoxyethy1)phenethylamine (4). Compounds 3 and 4 are useful for the preparation of important and valuable compounds, e. g. 1-(2-phenethyl)piperidine4-one and its derivatives, utilized in the synthesis of analgesics such as fentanyl,1-8 calfentanyl
苯乙胺 (1) 与丙烯酸甲酯 (2) 的反应分两步进行,生成 N-(P-carbomethoxyethy1) 苯乙胺 (3) 和 N,N-双-(P-carbomethoxyethy1) 苯乙胺 (4)。化合物3和4可用于制备重要且有价值的化合物,例如1-(2-苯乙基)哌啶4-酮及其衍生物,用于合成镇痛药如芬太尼、1-8卡芬太尼、3-甲基芬太尼~ny1 ,'~'~ 和芬太尼的内酰胺类似物。4
