763111-47-3,763111-47-3, 4-(4-Fluoro-3-(piperazine-1-carbonyl)benzyl)phthalazin-1(2H)-one is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 3: Preparation of 4-(4-fluoro-3-(4-(2-methyl-2-((5-(trifluoromethyl) pyridin-2- yl)oxy) propanoyl)piperazine-l-carbonyl) benzyl) phthalazin-l(2H)-one.To a solution of 2-methyl-2-((5-(trifluoromethyl)pyridin-2-yl)oxy)propanoic acid (0.204 g, 0.81 mmol) in dry DMF (6 mL) was added TBTU (0.289 g, 0.90 mmol) at room temperature under atmosphere of nitrogen. To this 4-(4-fluoro-3-(piperazine-l- carbonyl)benzyl)phthalazin-l(2H)-one (0.3 g, 0.81 mmol) and DIPEA (0.303 mL, 1.74 mmol) were added. The reaction mixture was stirred at room temperature for 2 h. The progress of reaction was checked by TLC by using mobile phase 5 % methanol in chloroform. The reaction mixture was diluted with ethyl acetate. The organic layer was washed with water, dried over anhydrous Na2S04 and solvents were evaporated on a rotatory evaporator under reduced pressure to crude solid which was purified by the flash column chromatography using eluent chloroform : methanol (98.3 : 1.7) to afford 4-(4-fluoro-3-(4-(2-methyl-2-((5-(trifluoromethyl) pyridin-2-yl)oxy) propanoyl)piperazine-l-carbonyl) benzyl) phthalazin-l(2H)-one as white solid (0.230 g, 47 %).
The synthetic route of 763111-47-3 has been constantly updated, and we look forward to future research findings.
