摘要
New reagents tor 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 amines with high purity. (C) 2002 Elsevier Science Ltd. All rights reserved.
