실험 절차

5-Amino-1-(4-fluorophenyl)-4-[3-hydroxybenzoyl]pyrazole, from Example 10, step 2, (0.30 g, 1.01 mmol) was combined with K2CO3 (0.418 g, 3.03 mmol) and THF (6 mL). The mixture was cooled in an ice bath and then isopropyl isocyanate (0.12 mL, 1.21 mmol) was added. The reaction was allowed to warm to room temperature and stirred for 16 hours. The reaction mixture was quenched with water, extracted into ethyl acetate: dried (MgSO4), filtered, and concentrated to dryness. The residue was stirred in methanol and dichloromethane for one hour then filtered to give 0.118 g of 5-amino-1-(4-fluorophenyl)-4-[3-isopropylaminocarbonyloxybenzoyl]pyrazole (mpt. 225.2-230.1° C.).
