NMR Study of the Solid-State Rearrangement of 3-Amino-1- and -2-(chloroacetyl)pyrazole to 3-(Chloroacetamido)pyrazole

Reaction of 3-aminopyrazole (1) with chloroacetyl chloride gives a mixture of 3-amino-1- and -2-(chloroacetyl)pyrazole (2 and 3), both of which rearrange in the solid-state to 3-(chloroacetamido)pyrazole (4) over a period of a few days.The course of the rearrangements was monitored directly by CP/MAS NMR and indirectly by 1H NMR spectroscopy; the results suggest that the mechanism involves 3 -> 2 -> 4. - Keywords: NMR, 13C CP/MAS, 1H Solid-state rearrangement, 3-Amino-1- and -2-(chloroacetyl)pyrazole
