실험 절차
Aqueous sodium hydroxide (2M) (2.5 eq) was added portionwise over 5 minutes to a stirred suspension of methyl 4-[4-(2-adamantylcarbamoyl)-5-tert-butyl-pyrazol-1-yl]benzoate (Intermediate #56) (1.0 eq) in methanol (10 vol) at 20° C. (exotherm 20-27° C.). The resulting suspension was heated to 70° C. (jacket temperature), (batch refluxes approx 60-65° C.) for 1 hour (complete by LCMS). The orange reaction mixture was cooled to 20° C. (solution remained slightly cloudy) and filtered through celite to remove a small amount of solids. The filtrate was then poured into a flange flask and water (25 vol) was added. The mixture was then adjusted to pH 3 with 2M HCl (approx 800-850 ml) (turns very thick). The aqueous was then filtered and the pale yellow solid washed with water, sucked dry overnight, and washed with acetonitrile and finally 1:1 acetonotrile/diethyl ether and dried under vacuum at 50° C. for 72 hours (weekend) to give 4-[4-(2-adamantylcarbamoyl)-5-tertbutyl-pyrazol-1-yl]benzoic acid (80%) as a solid.
