Reaktionsschritte

Additional compounds 22-29 were synthesized by the same procedure as described above (Examples 1 and 2) for Compound 2 except that in Example 1, alternative amines were used in place of L-tert-Leucine methylamide in the reaction with intermediate Intermediate 1I to form intermediate Intermediate 1J. For example, Compound 22 was synthesized in the same manner as Compound 2 except that (S)-2-amino-3,3-dimethylbutan-1-ol was used in place of L-tert-Leucine methylamide. Compound 23 was synthesized in the same manner as Compound 2 except that (R)-2-amino-3,3-dimethylbutan-1-ol was used in place of L-tert-Leucine methylamide. These resulting intermediates were deprotected with TFA, as described in Example 2, to form additional Compounds 22-29.
