Reaction Steps

[4-Chloro-2-(2-chloro-phenoxy)-pyrimidin-5-yl]-thiophen-2-yl-methanone (82 mg, 0.23 mmol) was dissolved in a mixture of 10 mL ethanol and 0.5 mL THF, and 15 mg of anhydrous hydrazine was added. The reaction mixture was stirred at room temperature for 10 minutes and then was heated to 80° C. for 20 minutes. Solvent was removed under reduced pressure, and the residue was purified by preparative scale TLC using 1.8% MeOH in methylene chloride to yield 36 mg of 6-(2-Chloro-phenoxy)-3-thiophen-2-yl-1H-pyrazolo[3,4-d]pyrimidine. Mass Spec. M+H=329. Mp=221.3-223.1° C.
