Participants

Reaction Steps

The title compound was prepared according to the procedure as set forth in example 151, except that 1-fluoro-2-isocyanatobenzene was used in place of 1-fluoro-3-isocyanatobenzene and methyl 2-(3-(4-aminophenyl)isoxazole-5-carboxamido)-3-phenylpropanoate was used in place of methyl 2-(3-(4-aminophenyl)isoxazole-5-carboxamido)-3-methylbutanoate to yield 88% of the title compound.
