Procedure

To a cooled (0° C.) mixture of 1.5 g (3.8 mmol) of methyl 2-[(2-aminobenzyl)-(4-methoxybenzenesulfonyl)amino]-3-hydroxypropionate and 2.7 ml (19 mmol) of triethylamine in 15 ml of CH2Cl2 was added 1.58 g (11.4 mol) of phenoxyacetyl chloride. The mixture was stirred at room temperature overnight and filtered. The filtrate was washed with H2O, 2 N citric acid, and brine and dried with Na2SO4. The solvent was removed to give 2.4 g of crude methyl 2-{(4-methoxybenzenesulfonyl)-[2-(phenoxyacetylamino)benzyl]amino}acrylate as an oil. Anal. for C26H26N2O7S: Calc'd: C, 61.2; H, 5.1; N, 5.5; Found: C, 62.6; H, 5.1; N, 4.0.
