실험 절차

The title compound was prepared by coupling (R)-α-(1,3-benzodioxol-5-yl)benzeneethanamine (preparation described in Step B of Example 60) with (R)-N-[3-[2-iodo-1-[(triethylsilyl)oxy]ethyl]-2-chlorophenyl]methanesulfonamide (prepared from 2-bromo-1-[4-chloro-3-[(methylsulfonyl)amino]phenyl]ethanone, preparation described in Example 69, utilizing the procedures described in step A-C of Example 19) following the procedure described in steps D and E of Example 19 with the following modifications. 1) Chromatography on silica gel using 25% EtOAc/hexane yielded (R), (R)-N-[5-[1-(triethylsilyl)oxy-2-[[1-(1,3-benzodioxol-5-yl)-2-phenylethyl]amino]ethyl]-2-chlorophenyl]methanesulfonamide. 2) In step E the title compound was eluted from silica gel using 1:1 EtOAc/hexane prior to final preparative HPLC purification (see Example 1 for HPLC protocol) eluting with 52% solvent B.
