带Boc的胺和2-氯吡啶(3倍摩尔量)加入DCM中,滴加三氟甲磺酸酐(1.5倍摩尔量),室温搅拌反应1 h,再加入醇(3倍摩尔量)、三乙胺(3倍摩尔量),室温反应1 h,制得相应的氨基甲酸酯。13例收率80%~93%。若加入硫醇(3倍摩尔量),室温反应1 h,得相应的硫代氨基甲酸酯。10例收率 The amine with Boc and 2-chloropyridine (3-fold molar amount) were added into DCM, trifluoromethanesulfonic anhydride (1.5-fold molar amount) was added dropwise and the reaction was stirred at room temperature for 1 hour. Ethylamine (3-fold molar amount), and reacted at room temperature for 1 h to obtain the corresponding carbamate. 13 cases of the yield of 80% to 93%. If thiol (3-fold molar amount) was added, the reaction was carried out at room temperature for 1 h to obtain the corresponding thiocarbamate. 10 cases of yield
