Reaction Steps

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (2.9 g) and 1-hydroxybenzotriazole hydrate (2.0 g) were added to a solution of 2-methoxyphenylamino acetonitrile (2.0 g) and N-tert-butoxycarbonyl L-leucine (2.5 g) in N,N-dimethylformamide (20 ml) at room temperature followed by N,N-diisopropylethylamine (5.3 ml) and stirred at room temperature overnight. The mixture was diluted with water, extracted into ethyl acetate and dried (MgSO4). The solvent was removed under vacuum to leave an oil which was subjected to column chromatography on silica eluting with isohexane/ethyl acetate 2:1 to give a colourless oil (3.7 g).
