実験手順

A slurry of 5-(3,5-Dioxo-4,5-dihydro-3H-[1,2,4]triazin-2-yl)-N-(1-hydroxy-cycloheptylmethyl)-2-methyl-benzamide (200.0 mg, 0.537 mmol) and Cs2CO3 (290.3 mg, 0.891 mmol) were stirred in DMSO (1.79 mL, 0.3 M) at ambient temperature for 15 minutes. 2-Bromoacetamide (74.1 mg, 0.537 mmol) was added and the reaction stirred at ambient temperature for 14 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 to a tan oil. The crude was triterated from IPE/Et2O/CH2Cl2 to give the title compound as a tan solid (105 mg). LCMS (m/z) 430.5 M+1.
