실험 절차

To a mixture of 6-tert-butyl-2-(4-chloro-3-(hydroxymethyl)pyridin-2-yl)-8-fluorophthalazin-1(2H)-one 104a (150 mg, 0.42 mmol) and triethylamine, Et3N (0.12 mL, 0.84 mmol) in tetrahydrofuran, THF (2.5 mL) was added acetyl chloride, AcCl (44 μl, 0.62 mmol). The mixture was stirred at rt for 1 h and quenched with water, extracted with ethylacetate, EA. The combined organic layers were dried over Na2SO4, filtered and concentrated to give 104b (160 mg) as a colorless oil. MS-ESI: [M+H]+ 404.1
