Reaction Steps
A solution of 2,2-dimethyl-3-oxo-pentanedinitrile (9 g, 66 mmol) and methyl-hydrazine (3 g, 66 mmol) in EtOH (100 mL) was treated with cone HCl (16.5 mL, 198 mmol) and the resulting mixture was refluxed overnight. The solvent was removed under reduced pressure and the residue was purified by chromatography to give 2-(5-amino-1-methyl-1 H-pyrazol-3-yl)-2-methylpropanenitrile (2.7 g, 25% yield), 1H NMR (300 MHz, CDCl3): δ 5.56 (s, 1 H), 3.63 (s, 3 H), 1.67 (s, 6 H); MS (ESI) m/z: 165.2 [M+H]+.
