Versuchsvorschrift

[1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II),complex with dichloromethane (1:1) (30.2 mg, 0.037 mmol) is added to a degassed mixture of the product of step 1, Example 21 along with 2,2-dichloro-N-[(1S,2R)-1-(fluoromethyl)-2-hydroxy-2-(4-iodophenyl)ethyl]acetamide (150 mg, 0.369 mmol), and cesium carbonate (482 mg, 1.48 mmol) in N,N-dimethylformamide (2.76 mL) at room temperature. The reaction mixture is heated at 60° C. for 4 hours. After cooling to room temperature the reaction mixture is concentrated under high vacuum, and the residue slurried in ethyl acetate. The slurry is filtered through solka floc washing the cake with ethyl acetate. The combined filtrates were concentrated and the brown residue purified by chromatography on silica gel eluting with a gradient of 50-80% ethyl acetate in hexanes to afford the title compound (72.5 mg): 1H NMR (300 MHz, DMSO-d6) δ 2.92-2.97 (m, 2H), 3.08-3.13 (m, 2H), 4.23-4.28 (m, 1.5 H), 4.41-4.46 (m, 0.5H), 4.54-4.58 (m, 0.5H), 4.69-4.74 (m, 0.5H), 4.89-4.92 (m, 1H), 5.98 (d, 1H), 6.53 (s, 1H), 7.42-7.49 (m, 3H), 7.79 (d, 2H), 8.03-8.06 (dd, 1H), 8.62 (d, 1H), 8.83-8.84 (m, 1H). MS (ESI+) m/z of 410.0/412.0 [M+H].
