A mixture of N-((6-bromothiazolo[5,4-b]pyridin-2-yl)methyl)methanesulfonamide (236 mg, 0.732 mmol), 2,2-difluoro-N-((1R,2S)-3-fluoro-1-hydroxy-1-(4-(trimethylstannyl)phenyl)propan-2-yl)acetamide (300 mg, 0.0.732 mmol) and tris(2-furyl)phosphine (34 mg, 0.146 mmol) and Tris(dibenzylideneacetone)dipalladium(0) (68 mg, 0.0732 mmol) in dimethylformamide (3 mL) is heated at 70° C. for 5 hours under nitrogen. The mixture is then cooled, diluted with water (10 mL) and extracted with ethyl acetate (3×15 mL). Extracts are dried over Na2SO4 and concentrated to get crude product. Obtained product purified by HPLC to give the title compound (90 mg): 1HNMR (DMSO-d6): 3.07 (s, 3H), 4.27-4.39 (m, 1.5H), 4.40-4.48 (m, 0.5H), 4.52-4.60 (m, 0.5H), 4.64-4.71 (m, 2.5H) 4.88-4.94 (m, 1H), 6.22 (t, 1H), 7.50 (d, 2H), 7.83 (d, 2H), 8.22-8.33 (m, 1H), 8.62 (bs, 1H), 8.85 (d, 1H), 8.94 (s, 1H). m/z (Cl) M+H 489.
