Procedure

A solution of 4.10 g of the product of Step E in 1,2-dichloroethane (142 mL) was treated with 5.60 g of aluminum trichloride and the suspension was heated to 80° C. After two h, the reaction mixture was cooled to ambient temperature and poured into ice water (500 g). After the ice had dissolved, the mixture was extracted with EtOAc and the organic layer was washed with sat. sodium chloride solution, dried over magnesium sulfate, filtered, and concentrated. The residue was purified by silica gel chromatography to afford 6-tert-butyl-8-chloro-2H-[1,2,4]triazolo[4,3-a]pyrazin-3-one as a yellow solid. MS (M+H+)=227.3.
