New reagents for the high yielding amidination of primary and secondary amines are described. By attaching a benzyl substituent to the 3,5-dimethyl-1H-pyrazole-1-carboxamidine ring, a reagent 1 is obtained which allows easy work-up after amidination because of solubility of byproducts in organic solvents. In addition, the polystyrene-bound analogue 2 was prepared which allows amidination of various
描述了用于伯胺和仲胺的高产率酰胺化的新试剂。通过将苄基取代基连接到3,5-二甲基-1 H-吡唑-1-羧am环上,获得试剂1,由于副产物在有机溶剂中的溶解性,该试剂1在酰胺化后易于后处理。另外,制备了聚苯乙烯结合的类似物2,其允许以高纯度酰胺化各种胺。
