Reaction Steps

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 N-4-aminophenyl-N'-propylurea to generate the title compound. The N-4-aminophenyl-N'-propylurea was prepared by sequentially treating commercial 4-nitrophenyl isocyanate with PrNH2 in THF at 20° C. followed by reduction with Na2S2O4 in THF/H2O at 100° C.
