HCID 866246963,3,3-Trifluoro-N-((S)-1-{2-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenylamino]-thiazol-4-yl}-3-methyl-butyl)-propionamide

Procedure

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. MS ISP (m/e): 482.1 (100) (M+H)+. 1H NMR (DMSO-D6, 250 MHz): δ (ppm)=10.39 (s, 1H), 8.50 (d, 1H), 7.91 (s, 1H), 7.66 (s, 1H), 7.24 (d, 1H), 7.03 (s, 1H), 7.01 (d, 1H), 6.64 (s, 1H), 4.92 (q, 1H), 3.82 (s, 3H), 2.14 (s, 3H), 1.75 (m, 1H), 1.62 (m, 2H), 0.91 (d, 3H), 0.88 (d, 3H).
