Procedure

To 0.8 g of N-[4-chloro-2-(2,6-difluorobenzyl)phenyl]-N-[(3,4-dimethoxyphenyl)sulfonyl]-β-alanine dissolved in 16 ml of tetrahydrofuran are added, at 0° C., 0.21 ml of N-ethylmorpholine and 0.16 ml of ethyl chloroformate. The mixture is left at room temperature for 1 hour, and 1.36 ml of ammonia (20%) in water are then introduced. After 48 hours at room temperature, the reaction medium is taken up in ethyl acetate and washed with water. The organic phase is dried over anhydrous sodium sulfate and concentrated, and the residue is chromatographed on a column of silica gel, eluting with a 98/2 (v/v) dichloromethane/methanol mixture to give 0.295 g of the expected product.
