실험 절차

Phosphoryl chloride (4.3 mL) was added dropwise to DMF (20 mL) at 0° C., and the mixture was stirred for 20 min. To the reaction mixture was added a solution of 6-chloro-N-cyclobutyl-N-methylpyrazin-2-amine (4.61 g) in DMF (5 mL), and the mixture was stirred at 50° C. for 15 hr. Water was added to the reaction mixture and the mixture was stirred for 2 hr and extracted with ethyl acetate. The extract was washed with water and saturated brine and dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (solvent gradient: 10→50% ethyl acetate/hexane) and recrystallized from hexane-diisopropyl ether to give the title compound (3.46 g, 66%).
