Amides, aldehydes and benzotriazole or morpholine react, with the elim
ination of water to form N-Mannich bases or N,N'-arylidene symmetrical
diamides in good or very good yields. We also found that amides, alde
hydes and 1,2,4-triazole react to form a new N-[1-(1H-1,2,4-triazol-1-
yl)alkyl]amides with a 58-85% yield.
