1,1-Dimethylhydrazine → HCID 69788456, compound

Participants

Reaction Steps

A solution of 4-[(2-oxocyclohexyl)methyl]-benzonitrile (7 g) (0.033 mol) and anhydrous N,N-dimethylhydrazine (9.2 ml) (3,7 eq.) in EtOH (100 ml) was refluxed for 8 h. After cooling, the reaction mixture was concentrated to dryness. The residue was partitioned between tBuOMe and water, the organic phase washed twice with water, dried over magnesium sulfate, and concentrated to yield 4-[[2-(dimethylhydrazono)cyclohexyl]methyl]-benzonitrile (6.1 g) as a orange oil. 1H NMR (CDCl3): 7.55 (2H, d), 7.30 (2H, d), 3.15 (1H, dd), 2.9-2.15 (6H, m), 2.3 (6H, s), 1.8-1.3 (4H, m).
