75884-70-7, 6-Bromophthalazin-1(2H)-one is a phthalazine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A dry 2-neck flask was evacuated and backflushed with argon (3X). Sodium t-butoxide (360 mg, 3.75 mmol), 6-bromophthalazin-l(2H)-one (338 mg, 1.5 mmol), (4-cyclohexylphenyl)methanamine (340 mg, 1.8 mmol), (+/-)BINAP (280 mg, 0.45 mmol) and Pd2(dba)3 (137 mg, 0.15 mmol) were added to the flask. Toluene (30 mL) was then added and the mixture was degassed with stirring under vacuum and backflushed with argon (3X). The reaction mixture was stirred at reflux for 3 hours and then allowed to cool to room temperature. The reaction mixture was poured onto water and EtOAc and extracted with EtOAc (3X) and then extracted with DCM (2X). The combined organic extract was washed with brine, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The crude residue was slurred in DCM and filtered and the solid cake washed several times with DCM. The combined filtrate and washes were concentrated in vacuo to provide crude product, 6-((4-cyclohexylbenzyl)amino)phthalazin-l(2H)-one, as an off-white powder (118 mg).
The synthetic route of 75884-70-7 has been constantly updated, and we look forward to future research findings.
