실험 절차

Following the procedure described in part E of Example 1 (R), (S)-α-[[2-[((1,1-dimethylethyl)dimethylsilyl)oxy]-2-[4-hydroxy-3-[(methylsulfonyl)amino]phenyl]ethyl]amino]-4-methoxybenzeneacetic acid was condensed with 3-[(dimethylamino)sulfonyl]aniline to generate the title compound. The 3-[(dimethylamino)sulfonyl]aniline was prepared by sequential treatment of commercial 3-nitrobenzenesulfonyl chloride with Me2NH in CH2Cl2 containing (i-Pr)2NEt followed by reduction with SnCl2 in EtOAc at 20° C.
