Reaction Steps
Sodium iodide (4.06 kg, 27.1 mol) was added to the THF/toluene solution of methanesulfonic acid 5-(3,4-dichlorophenyl)-1-(4-methoxyphenyl)-1H-pyrazol-3-ylmethyl ester (Example 517, 6.32 kg, 14.8 mol). The resulting reaction mixture was heated at 40° C. for 6 h and then allowed to cool to rt overnight. When HPLC analysis indicated the disappearance of the starting material, the reaction was quenched with 28% aq. sodium thiosulfate (6.3 L). The organic layer was washed with sat. aq. NaHCO3 (6.3 L), brine (6.3 L), then dried (MgSO4). After filtration to remove the drying agent, the desired product was obtained in a solution, which was used in the next synthetic step without isolation. Chemical characterization data obtained herein for the title compound is not duplicated in this Example in light of the same data given in Example 1, Step E.
