EXAMPLE A.4. Compound c-3 (127l): 4-(4-fluoro-3-(4-(2-(3-iodophenyl)acetyl)piperazine-l-carbonyl)- benzyl)phthalazin-l(2H)-one. A solution of 3-iodophenyl acetic acid (6.5 mg, 0.048 mmol), l-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) (10.5 mg, 0.055 mmol), N-hydroxy succinimide (NHS) and 600 mu DM F was stirred for 30 min at room temperature. Then, 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. The reaction was washed with 500 mu of H20 and extracted with 500 mu dichloromethane (DCM). The resulting organic solution was purified on silica gel, using a gradient elution from neat DCM to DCM/hexane 5:1 to obtain the desired product as a white solid (3 mg, 20% yield). 1H NMR (CDCI3) delta = 9,82 (s, 1H), 8.40-8.38 (m, 1H), 7.71-7.69 (m, 2H), 7.55-7.53 (m, 1H), 7.51-7.50 (m, 2H), 7.25-7.24 (m, 2H), 7.09-6.90 (m, 3H), 4.20 (s, 2H), 3.64-3.31 (m, 8H), 2.84 (s, 2H). LC-ESI-MS (+) m/z = 633.1 [M+Na+]+. HRMS-ESI [M+H+]+ m/z calculated for [C28H24FIN403]+ 611.0955, found 611.0948.
With the rapid development of chemical substances, we look forward to future research findings about 763111-47-3
