실험 절차

To a suspension of 1-[3-(4-pyridin-4-yl-1H-pyrazol-3-yl)-phenyl]-3-(4-trifluoromethyl-phenyl)-urea (100 mg, 0.236 mmol) (prepared as described in Example 6) in THF (10 mL) DIPEA (61 mg, 81 uL, 0.427 mmol) was added. The mixture was stirred for 5 minutes before adding ethyl chloroformate (31 mg, 27 uL, 0.283 mmol). After 2 hours the mixture was evaporated to dryness, taken up with ethyl acetate and washed three times with water. The organic phase was dried over Na2SO4, evaporated to dryness and triturated with diisopropyl ether to yield 4-pyridin-4-yl-3-{3-[3-(4-trifluoromethyl-phenyl)-ureido]-phenyl}-pyrazole-1-carboxylic acid ethyl ester (90 mg, 77%).
