Reaction Steps

To a solution of N-{4-[5-(1-Allyl-1H-imidazol-2-yl)-4-(2,4-dichlorophenyl)-1,3-thiazol-2-yl]pyridin-2-yl}acetamide (0.0650 g, 0.138 mmol) in dichloromethane (1.0 mL) and acetic acid (0.34 mL) was added tetrakis(triphenylphosphine)palladium(0) (0.00798 g, 0.00691 mmol) followed by phenylsilane (0.0870 mL, 0.706 mmol). The solution was stirred at 40° C. for 90 minutes. The solution was cooled to room temperature then concentrated in vacuo and diluted with ethyl acetate and saturated sodium bicarbonate solution. The layers were separated and the aqueous phase was extracted 3 more times with ethyl acetate. The organic extracts were washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. Column chromatography was performed to yield the title compound (0.0380 g, 64%). LCMS: (FA) ES+, 431, 433. 1H NMR (400 MHz, d4-Methanol) δ: 8.75-8.70 (m, 1H), 8.44-8.39 (m, 1H), 7.70-7.44 (m, 4H), 7.13-7.07 (m, 2H), 2.20 (s, 3H).
