The product was prepared from methyl 2-amino-5-methyl-1,3-thiazole-4-carboxylate (25 mg, 0.15 mmol), and 5-chloro-4-(2,5-difluorophenyl)thiophene-2-sulfonyl chloride (Intermediate 20) (48 mg, 0.15 mmol) according to the General Procedure 11, described in Example 131. The crude product was purified using reversed phase chromatography (ACE C8, 5 μm, 21×50 mm, flow 25 ml/min, gradient: H20.1% TFA in water/MeCN over 6 minutes). The title compound was obtained in 21% yield (14.1 mg). 1H NMR (400 MHz, MeOH-d4) δ ppm 2.56 (s, 3 H) 7.17-7.30 (m, 3 H) 7.55 (d, J=1.76 Hz, 1 H). MS (ESI+) m/z 451 [M+H]+.
