실험 절차

2-Fluoro-5-[(4-oxo-3H-phthalazin-1-yl)methyl]benzoic acid 1a (170 mg, 0.57 mmol) was dissolved in 10 mL of N,N-dimethylformamide, followed by addition of O-(1-benzotriazolyl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (323 mg, 0.85 mmol), 5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyrazine hydrochloride 17a (100 mg, 0.63 mmol, prepared according to a known method “Journal of Medicinal Chemistry, 2005, 48(1), 141-151”) and N,N-diisopropylethylamine (302 mg, 1.70 mmol). After stirring for 12 hours, the reaction mixture was concentrated under reduced pressure and the resulting residue was purified by thin layer chromatography with elution system A to obtain 4-[[3-(6,8-dihydro-5H-[1,2,4]triazolo[4,3-a]pyrazine-7-carbonyl)-4-fluoro-phenyl]methyl]-2H-phthalazin-1-one 17 (50 mg, yield 21.7%) as a light yellow solid.
