Reaction Steps

A solution of 300 mg of the product of Step A in AcOH (5.0 mL) was heated at reflux for two h. The solvent was removed to afford 2-tert-butyl-6-isopropyl-8-isopropylamino-2H-[1,2,4]triazolo[4,3-a]pyrazin-3-one as a light green solid. A suspension of 240 mg of this product and 329 mg of aluminum trichloride in dichloroethane (10.0 mL) was heated at reflux for two h. The reaction was poured into water and the resulting solution was extracted with EtOAc. The organic extract was dried over magnesium sulfate, filtered, and concentrated and the residue was purified by silica gel chromatography to afford the title compound as an off-white solid. MS (M+H+)=234.1.
