The downstream synthesis method of this compound is introduced below.<\/p>\n<p>A solution of compound 9 (56 mg, 0.12 mmol, 1.0 equiv) in anhydrous DMF (0.2 mL) was treated with 60% sodium hydride (6.0 mg, 0.15 mmol, 1.2 equiv) at room temperature. After stirring at this temperature for 5 min, 5-(chloromethyl)-l,3-dimethyl- lH-pyrazole (21 mg, 0.14 mmol, 1.1 equiv) was introduced. Then the mixture was stirred at room temperature for 1 hour. The reaction was quenched with saturated aqueous NaHCO3 solution. The resultant solution was extracted with ethyl acetate. The combined organic extracts were washed once with brine, dried over Na2SO4, filtered and concentrated in vacuo. The residue was chromatographed on prep-TLC (ethyl acetate\/dichloromethane\/methanol 20:20:1, 2 runs) to afford compound 11 (27 mg, 39 %) as an oil.
