실험 절차

N-[3-{2-[(5-bromo-2-pyrimidinyl)oxy]ethoxy}-1-methyl-4-(4-methylphenyl)-1H-pyrazol-5-yl]-5-isopropylpyridine-2-sulfonamide (Example 41) (393 mg), powdered sodium formate (68 mg) and dichlorobis(triphenylphosphine)palladium (II) (9.4 mg) were placed in a Wheaton® vial (2.5 ml) volume containing a stirring vane. Dimethylformamide (2.0 ml) which had been saturated with carbon monoxide gas at room temperature, was added to the vial so as to produce a yellow solution. The sealed vial was magnetically stirred at 100° C. (oil bath temperature) for 3 hours before being left to cool to room temperature. A TLC check showed the presence of a significant amount of starting material. Addition of dichlorobis(triphenylphosphine)palladium (II) (9.4 mg) and resaturation of the dimethylformamide with carbon monoxide was followed by heating of the vial's contents for a further hour. On cooling to room temperature, the solution was degassed by bubbling nitrogen gas through it. The mixture was treated with ethyl acetate and filtered through a bed of Celite™ (5 g), followed by washing the Celite with ethyl acetate so as to take the solution volume to 100 ml. Washing of this phase with water (3×100 ml) and brine (100 ml), was followed by drying (Na2SO4), filtering and concentration in vacuo. This afforded the title compound as white crystals (157 mg).
