Electric Literature of 675109-26-9, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 675109-26-9 name is 6-Bromoisoindolin-1-one, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
A mixture of 78 6-bromoisoindolin-1-one (5.0 g, 23.58 mmol), 176 Pd(AcO)2 (528 mg, 2.30 mmol), Xantphos (1.36 g, 2.36 mmol) and 177 TEA (1.19 g, 117.9 mmol) in 170 methanol (100 mL) was heated to 70 C. under 1 atm of 178 CO (gas) overnight. The reaction mixture was filtered and the filtrate was concentrated under vacuum. The residue was purified by silica column chromatography (1%-2% 23 MeOH in 31 DCM) to give 72A (500 mg, 11% yield) as a white 179 solid: ESI m/z 192.1 [M+H]+ .
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 6-Bromoisoindolin-1-one, and friends who are interested can also refer to it.
