Procedure
Methanesulphonyl chloride was added slowly at 0° C. to a solution of the ethyl (RS)-(4-cyano-phenylamino)-(3-ethoxy-5-hydroxymethyl-phenyl)-acetate (200 mg, 0.564 mmol) obtained in Example 234.2 and N-ethyldiisopropylamine (88 mg, 0.68 mmol) in THF (3 ml). The mixture was stirred for 1.5 h. at 0° C. and for 1.5 h. at room temperature. The mixture was poured into ice-water/1M HCl and extracted with EtOAc. The organic phase was washed with H2O, dried and filtered, and the filtrate was concentrated. There were obtained 232 mg of ethyl (RS)-(4-cyano-phenylamino)-(3-ethoxy-5-methanesulphonyloxymethyl-phenyl)-acetate as a yellow oil, which was used for the next reaction without additional purification.
