With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.763111-47-3,4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one,as a common compound, the synthetic route is as follows.
EXAMPLE A.5. A solution of 4-iodophenyl acetic acid (6.5 mg, 0.048 mmol), EDC (10.5 mg, 0.055 mmol), NHS and 600 mu DMF was stirred for 30 min at room temperature. After this time, the 4-(4-fluoro-3- (piperazine-l-carbonyl)benzyl)phthalazin-l(2H)-one (10 mg, 0.0275 mmol) was added to the solution and the mixture was stirred at room temperature overnight. H20 (500 mu) was added, the mixture extracted with DCM (2 x 500 mu), and the combined extracts dried under vacuum. The crude mixture was purified by silica column chromatography (100% DCM), and the product obtained as a white solid (8.8 mg, 61%). 1H NMR (CDCI3) delta = 9.82 (s, 1H), 8.40-8.38 (m, 1H), 7.83-7.81 (d, 1H), 7.77- 7.75 (d, 1H), 7.70-7.69 (m, 2H), 7.63-7.56 (m, 3H), 7.00-6.89 (m, 3H), 4.20 (s, 2H), 3.63-3.11 (m, 8H), 2.84 (s, 2H). LC-ESI-MS (+) m/z = 632.9 [M+Na+]+. HRMS-ESI [M+H+]+ m/z calculated for [C28H24FIN403]+ 611.0955, found 611.0971.
763111-47-3 4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one 11726399, aphthalazine compound, is more and more widely used in various.
