実験手順

A solution of 1-[[(phenylmethoxy)carbonyl]amino]pentylphosphinic acid (490 mg., 1.72 mmole) and 1-[(S)-2-hydroxy-1-oxopropyl]-L-proline, phenylmethyl ester (255 mg., 0.92 mmole) in dry tetrahydrofuran (5 ml.) is treated with dicyclohexylcarbodiimide (285 mg., 1.38 mmole) and dimethylaminopyridine (50 mg.) and stirred at room temperature for 2.5 hours. The mixture is filtered, diluted with ethyl acetate, and washed successively with 5% potassium bisulfate, saturated sodium bicarbonate, and saturated sodium chloride solutions, dried over sodium sulfate, and evaporated to give crude (S)-1-[2-[[[1-[[(phenylmethoxy)carbonyl]amino]pentyl]phosphinyl]oxy]-1-oxopropyl]-L-proline, phenylmethyl ester.
