Solvent-free synthesis of azole carboximidamides.

A one-pot procedure is described for the preparation of 1H-pyrazole-carboximidamides 2, 1 H-benzotriazole-carboximidamides 3 and guanidinylation of amines with 3. The X-ray crystal structure of N,N-dimethyl- 1 H-benzotriazole- 1 -carboximidamide 3b, has been determined.
