Procedure

A mixture of 5-bromo-2-(1-(methylsulfonyl)pyrrolidin-2-yl)pyridine (100 mg, 0.328 mmol), 2,2-dichloro-N-((1R,2S)-3-fluoro-1-hydroxy-1-(4-(trimethylstannyl)-phenyl)-propan-2-yl)acetamide (145 mg, 0.328 mmol) and tris(2-furyl)phosphine (15.5 mg, 0.066 mmol) is dissolved in N-methylpyrrolidinone (1.6 mL) and deoxygenated. Tris(dibenzyliden-eacetone) dipalladium(0) (30.5 mg, 0.033 mmol) is then added and the mixture is heated to 80° C. overnight. The mixture is then cooled and purified by preparative hplc (Prep HPLC=Waters, Column=Gemini NX C18 21×150 mm 5 um, MP A=0.1% trifluoroacetic acid in water MP B=acetonitrile, Gradient 10% B to 50% in 10 min holding for 2 min, 20 mL/min.) Fractions are dried on rotovap and freeze-dried with 1,4-dioxane to give the title compound (33 mg): 1H NMR (400 MHz, DMSO-d6) 1.9-2.0 (m, 2H), 2.0-2.1 (m, 1H), 2.3-2.4 (m, 1H), 3.0 (s, 3H), 3.5-3.6 (m, 2H), 4.15-4.35 (m, 1.5H), 4.45 (t, 0.5H), 4.55-4.65 (m, 0.5H), 4.7-4.75 (m, 0.5H), 4.9-5.0 (m, 2H), 6.5 (s, 1H), 7.5 (d, 2H), 7.65 (d, 1H), 7.75 (d, 2H), 8.2 (dd, 1H), 8.6 (d, 1H), 8.85 (d, 1H). m/z (Cl) M+H 504+506.
