실험 절차

0.8 g of 5-(3,4-dimethoxyphenyl)-2-{1-[(3-hydroxyphenyl)carbonyl]piperidin-4-yl}-4,4-dimethyl-2,4-dihydro-3H-pyrazol-3-one (compound described in example 76) and 0.75 g potassium carbonate are suspended in 10 ml of DMF. 0.4 g of 1,1,1-trifluoro-2-iodoethane are added and the reaction mixture is heated to 100° C. for 8 h until the reaction is completed according to TLC analysis. The solvent is evaporated under reduced pressure, and the remaining residue is taken up in DCM. The organic phase is washed with water, dried over MgSO4, and the solvent is removed under reduced pressure. Purification of the resulting crude product by column chromatography (silica gel and EA/PE/TEA=10:10:1) and by crystallization from diethyl ether yields the title compound.
