Participants

Reaction Steps

To (2S)-2-[(4-bromobenzyl)amino]-4-methylpentanoic acid (1.343 g, 4.62 mmol), PyBOP (2.65 g, 5.08 mmol), aminoacetonitrile hydrochloride (940 mg, 10.16 mmol) in dry DMF (30 mL) under dry nitrogen was added triethylamine (2.2 mL, 15.71 mmol) dropwise and the reaction was stirred for 4 hours. Aqueous sat. NaHCO3 was added and the product extracted with Et2O (2×), dried on Na2SO4, concentrated in vacuo, and purified by flash chromatography over silica gel (EtOAc/Hex, 4/6 then 1/1) to afford (2S)-2-[(4-bromobenzyl)amino]-N-(cyanomethyl)-4-methylpentanamide.
