실험 절차

A slurry of 2-Chloro-N-(1-hydroxy-cycloheptylmethyl)-5-(5-oxo-4,5-dihydro-[1,2,4]triazol-1-yl)-benzamide (44.4 mg, 0.122 mmol) and Cs2CO3 (66.0 mg, 0.202 mmol) were stirred in DMSO (0.813 mL) at ambient temperature for 20 minutes. 2-Bromoethyl methyl ether (17.0 mg, 0.122 mmol) was added and the reaction stirred at ambient temperature for 48 hours. The reaction was diluted with water (15-fold) and the aqueous extracted with CH2Cl2 (3×). The organics were dried over sodium sulfate, and concentrated in vacuo. The crude was purified by reverse phase HPLC reverse phase HPLC using a (25–65% gradient of 0.1% formic acid in acetonitrile and 0.1% formic acid in water) (to give the title compound (18 mg). LCMS (m/z) 423.5 M+1.
