ted 4-iodo-2,5-dimethoxyphenethylamine (7) in almost quantitative yield within only 1 h. Removal of the Me3Si group was accomplished with Bu4NF. Final N-deprotection by NaOH treatment afforded the novel phenethylamine 1 in an overall yield of 88%.
开发了一种简单而有效的制备4-乙炔基-2,5-二甲氧基苯乙胺(= 4-乙炔基-2,5-二甲氧基苯乙胺; 2C-YN; 1)的途径,这是有效的5-HT 2A /的乙炔基类似物C激动剂,例如4-碘-2,5-二甲氧基苯丙胺(DOI; 2b)。乙炔基部分是通过Pd催化的(三甲基甲硅烷基)乙炔与N-(三氟乙酰基)保护的4-碘-2,5-二甲氧基苯乙胺(7)的Sonogashira反应在1小时内以几乎定量的产率引入的。用Bu 4 NF除去Me 3 Si基团。决赛N通过NaOH处理的β-脱保护得到了新颖的苯乙胺1,总产率为88%。
