실험 절차

2-Fluoro-5-[(4-oxo-3H-phthalazin-1-yl)methyl]benzoic acid 1a (390 mg, 1.30 mmol) was dissolved in 10 mL of N,N-dimethylformamide, followed by addition of O-(1-benzotriazolyl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (983 mg, 2.60 mmol), crude morpholino-[3-(trifluoromethyl)-5,6,7,8-tetrahydroimidazo[1,5-a]pyrazin-1-yl]methanone 20d (400 mg, 1.30 mmol) and N, N-diisopropylethylamine (0.7 mL, 3.90 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-[[4-fluoro-3-[1-(morpholine-4-carbonyl)-3-(trifluoromethyl)-6,8-dihydro-5H-imidazo[1,5-a]pyrazine-7-carbonyl]phenyl]methyl]-2H-phthalazin-1-one 20 (150 mg, yield 20.0%) as a light yellow solid.
