Ammonium Acetate → HCID 68292043, compound

Reaction equation

[CH3:1][C:2]1([C:8]#[N:9])[CH2:6][CH2:5][CH2:4][C:3]1=O.C([O-])(=O)C.[NH4+].C([BH3-])#[N:16].[Na+]>CO>[NH2:16][CH:3]1[CH2:4][CH2:5][CH2:6][C:2]1([CH3:1])[C:8]#[N:9]

Procedure

A mixture of 1-methyl-2-oxocyclopentanecarbonitrile (272 mg, 2.209 mmol, from Step 1) and ammonium acetate (917 mg, 11.90 mmol) in methanol (2 mL) was stirred at room temperature for 2 h. Sodium cyanoborohydride (69.4 mg, 1.104 mmol) was added. After 17 h at room temperature, the mixture was concentrated. The residue was dissolved in water and ethyl acetate and stirred vigorously. The ethyl acetate phase was separated, dried (MgSO4), filtered and concentrated to give crude 2-amino-1-methylcyclopentanecarbonitrile (0.2436 g), which was taken to the next reaction without purification.
