Reaction Steps

A mixture of 4-pentynoic acid (2.00 g; 20.4 mmol) and 4-methylmorpholine (2.24 ml; 20.4 mmol) in DCM (20 ml) is cooled to −5° C. Isobutyl chloroformate (2.68 ml; 20.4 mmol) is added, followed by DMF (10 ml). The resulting mixture is added in portions to a solution of diethanolamine (2.25 g; 21.4 mmol) in DCM (10 ml). The resulting mixture is stirred overnight and evaporated. The residue is purified by silica gel column chromatography (gradient: DCM/methanol 100:0→82:18 to yield N,N-bis(2-hydroxyethyl)pent-4-ynamide.
