h)N-甲基-N-(3-[((N-叔丁氧羰基-N-甲基氨基)乙酰氧基)甲基]吡啶-2-基)氨基甲酸(1-氯乙基)酯的制备:将2-甲胺基-3-吡啶甲醇(22g,0.159mol)和二异丙胺(36.1mL,0.207mol,1.3当量)溶解于二氯甲烷(1L)中,并在乙醇-冰浴中冷却至约-13℃。在1小时内缓慢滴加1-氯乙基氯甲酸酯(17.5mL,0.161mol,1.01当量),滴加完毕后继续搅拌反应混合物1小时。随后加入2-((叔丁氧羰基)(甲基)氨基)乙酸(39.2g,0.207mol,1.3当量)和WSC(39.7g,0.207mol,1.3当量),分批次在10分钟内加入。加入DMAP(5.8g,0.047mol,0.3当量)后,将反应混合物于-7℃下搅拌2小时。反应完成后,将混合物升温至25℃并浓缩,残余物溶解于二乙醚(1L)中。将醚溶液转移至分液漏斗,依次用0.1N HCl(500mL×3)、水(500mL)、饱和NaHCO3水溶液(500mL)和饱和盐水(500mL×2)洗涤。有机相经无水MgSO4干燥后,减压浓缩得到粗产物(48.2g,收率约72.9%),无需进一步纯化即可用于后续反应。1H-NMR(270MHz,CDCl3):δ1.42(9H,d,J=24.1Hz),1.57(1.5H,br.s),1.88(1.5H,br.s),2.94(3H,s),3.37(3H,s),4.00(2H,d,J=21.1Hz),5.18(2H,d,J=13.5Hz),6.58(1H,q,J=5.45,11.0Hz),7.30(1H,s),7.82(1H,d,J=6.9Hz),8.47(1H,s);FAB-MS:m/z 416(M+H)+。
