Reaction Steps

The title compound was prepared in analogy to example 36 from 96 mg (0.2 mmol) [4-((S)-1-amino-3-methyl-butyl)-thiazol-2-yl]-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-amine trihydrochloride and 30 mg (0.2 mmol) 3,3,3-trifluoropropionylchloride. The crude product was purified on silica gel with methylene chloride/methanol 19/1 yielding 32 mg (33%) 3,3,3-trifluoro-N—((S)-1-{2-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenylamino]-thiazol-4-yl}-3-methyl-butyl)-propionamide as a yellow solid.
