Procedure

The title compound was prepared as in the previous Example starting from 5-{2-[5-(3,4-dichlorophenyl)furan-2-yl]ethylcarbamoyl}-1H-pyrazole-3-carboxylic acid and 4-piperidine ethanol. The crude product was purified by flash chromatography using CH2Cl2-MeOH as a gradient eluent (100:0-95:5). 1H NMR (400 MHz, CDCl3): 1.27 (3H, m), 1.57 (2H, m), 1.85 (3H, m), 2.81 (1H, m), 3.01 (2H, t), about 3.21 (1H, m), 3.76 (4H, m), about 4.41 (1H, m), about 4.67 (1H, m), 6.20 (1H, d), 6.59 (1H, d), 7.02 (1H, s), 7.29 (1H, broad s), 7.40 (1H, distorted d), 7.43 (1H, distorted dd), 7.75 (1H, d), 11.4 (1H, broad s).
