Reaction Steps

5-[3-(3,5-Difluoro-phenyl)-1-phenyl-1H-pyrazol-4-ylmethylene]-thiazolidine-2,4-dione (Compound No. 58, 0.10 g, 0.21 mmol) was dissolved in 1.0 mL of anhydrous dimethylformamide. Sodium carbonate (26.50 mg, 0.25 mmol) was added under nitrogen atmosphere and iodomethane (20.00 μL, 0.32 mmol) was added 10 minutes later. The mixture was stirred for 2 hours at room temperature. Water was added after the reaction was completed. The resultant solid was washed with water (10 mL×3 times). The solid was dried to obtain 90.0 mg (87%) of the target product.
