실험 절차

N,N-dicyclohexylcarbodiimide (0.216 g, 1.05 mmol) and 1-hydroxybenzotriazole (0.027 g, 0.2 mol) were added to a solution of 2-chloro-4-[[(3-methoxymethoxybenzyl) amino]carbonyl]benzoic acid (Example 124; 0.34 g, 1.0 mmol) and rac.-2-(dimethoxyphosphinyl)glycine methyl ester (Example 125; 197 mg, 1.0 mmol) in N,N-dimethylformamide (5 mL). The solution was stirred for 12 h, then was filtered and diluted with ethyl acetate. The resulting solution was washed with water, dried (Na2SO4), evaporated and the residual material was chromatographed (50-80% ethyl acetate/hexanes) to give rac.-N-[2-chloro-4-[[(3-methoxymethoxybenzyl) amino]carbonyl]benzoyl]-2-(dimethoxyphosphinyl)glycine methyl ester (0.24 g, 45% yield).
