Versuchsvorschrift

A mixture of 4-chloro-1-(4-(2-hydroxy-2-methylpropoxy)-3-methoxyphenyl)pyridin-2(1H)-one Part D of Procedure 9 (100 mg, 0.31 mmol), tributyl((4-chlorophenyl)ethynyl)stannane Part A (237 mg, 0.56 mmol), copper (I) iodide (17.6 mg, 0.09 mmol), and PalladiumTetrakis (54 mg, 0.05 mmol) in DMF (1.5 mL) was stirred under nitrogen at 70° C. overnight. The reaction was diluted with DCM, filtered, washed with 1N HCl, sat. NaHCO3, dried (MgSO4), and concentrated. The residue was purified using ISCO flash chromatography (silica gel/hexanes/ethyl acetate 100:0 to 0:100 gradient). The product was repurified using HPLC (Phen Luna Axia C18 5μ 10:90:0.1 to 90:100.1 MeOH—H2O-TFA) to afford the desired product 4-((4-chlorophenyl)ethynyl)-1-(4-(2-hydroxy-2-methylpropoxy)-3-methoxyphenyepyridin-2(1H)-one F-4 (90 mg, 0.21 mmol, 66.7% yield) as a light yellow solid. LC/MS 424 (M+H)+, tR 1.00 min (method 5). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 7.49-7.54 (2H, m), 7.37-7.44 (3H, m), 6.96-7.02 (2H, m), 6.93 (1H, d, J=2.26 Hz), 6.89 (1H, dd), 6.50 (1H, d, Hz), 3.88 (5H, s), 1.38 (6H, s)
