[0001187] To a solution of 4-bromo-lH-pyrazole (2.92 g, 20.0 mmol) in anhydrous DMF (50 mL) was added 2-bromopropane (3.69 g, 30.0 mmol) and potassium carbonate (6.90 g, 50 mmol) at room temperature. The reaction mixture was stirred for 10 h. The mixture was diluted with water (100 mL) and extracted with ethyl acetate (150 mL x 3). The combined organic extracts were washed with brine (150 mL x 2) and dried over anhydrous sodium sulfate. After filtration, the solvent was removed in vacuo and the residue was purified with flash column chromatography on silica gel to give Compound 330A.
