実験手順
Triethylamine (3.25 L, 23.3 mol) was added to a solution containing [5-(3,4-dichlorophenyl)-1-(4-methoxyphenyl)-1H-pyrazol-3-yl]-methanol (Example 516, 5.18 kg, 14.8 mol) in THF (25.2 L) and toluene (6.3 L) at rt under N2. The reaction mixture was heated to 35° C. and methanesulfonyl chloride (1.82 L, 23.5 mol) was added slowly maintaining the temperature between 35-45° C. The reaction mixture was stirred for an additional 2 h at 45° C. When HPLC analysis indicated the disappearance of the starting material, the reaction mixture was cooled to rt and quenched with 10% aq. NaCl (6.3 L). The organic layer was washed with brine (5.0 L) and the desired mesylate was used in solution in the next synthetic step without isolation. Data compared favorably with that obtained for Example 1, Step D.
