Hydrazine → 5-(2-Furyl)-3-methyl-1H-pyrazole

Participants

Reaction Steps

To a solution of 1.07 g (7.03 mmol) of 1-(2-furyl)-1,3-butanedione in 26 mL of MeOH at 25° C. was added 0.442 mL (14.07 mmol) of hydrazine. The reaction was stirred for 24 h then concentrated in vacuo. The residue was purified by silica gel flash column chromatography using hexanes/EtOAc (1:1) as eluent to give 1.02 g (98%) of title compound: low resolution MS (Cl) m/e 149 (MH+).
