Reaction Steps

The title compound was prepared in analogy to Example 1, replacing (2-amino-4,5-difluoro-phenyl)-carbamic acid tert-butyl ester with (2-amino-4-chloro-5-fluoro-phenyl)-carbamic acid tert-butyl ester (([CAS RN 579474-50-3]), Example 47), cyclohexanecarbaldehyde with piperonal ([CAS RN 120-57-0]), (3-chloro-phenyl)-acetic acid with DL- -methoxyphenylacetic acid ([CAS RN 7021-09-2]) and cyclohexyl isocyanide with cyclopentyl isocyanide ([CAS RN 68498-54-4]). MS (ISP): 570.2 [M+H]+.
