HCID 86656495(R)-Methyl 3-methyl-2-(3-(4-(3-p-tolylureido)phenyl)isoxazole-5-carbothioamido)butanoateYield 65%

Procedure

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. MS (ESI): m/z 467(M+H); 1HNMR (DMSO-d6, 300 MHz): δ 10.924 (d, 1H), 8.902 (s, 1H), 8.630 (s, 1H), 7.865 (d, 2H), 7.607(d, 3H), 7.351(d, 2H), 7.094(d, 2H), 4.810 (s, 1H), 3.665(s, 3H), 2.489 (m, 1H), 2.367(s, 3H), 1.033(m, 6H).
