Reaction Steps

The title compound was prepared according to the procedure as set, forth in example 151, except that 1-isocyanato-4-methylbenzene was used in place of 1-fluoro-3-isocyanatobenzene and (R)-methyl 2-(3-(4-aminophenyl)isoxazole-5-carbothioamido)-3-methylbutanoate was used in place of methyl 2-(3-(4-aminophenyl)isoxazole-5-carboxamido)-3-methylbutanoate to yield 65% of the title compound.
