実験手順

A mixture of 4-dimethylaminopyridine (DMAP; 197 mg, 1.61 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC.HCl; 309 mg, 1.61 mmol) was added to a stirred solution of diethylphosphonoacetic acid (129 μL, 0.805 mmol) and (2-(2-(2-(4-(1-aminobutyl)phenoxy)ethoxy)ethoxy)ethyl)imidodicarbonic acid, 1,3-bis-tert-butyl ester (45; 400 mg, 0.805 mmol) in N,N-dimethylformamide (10 mL). The resulting mixture was stirred under nitrogen for 3 hours at room temperature, and then poured into 100 mL of ethyl acetate. This solution was washed with 1N aqueous HCl (2×) and sat. brine, dried over sodium sulfate, and concentrated to an oil. Purification by flash silica gel column chromatography, eluting with ethyl acetate, afforded 49 (540 mg, quantitative) as a clear oil: MS (ES+) m/z 675.3 (M+H)+.
