Adding a certain compound to certain chemical reactions, such as: 552330-86-6, name is 5-Bromoisoindolin-1-one, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 552330-86-6, COA of Formula: C8H6BrNO
Step 1: 5-(Methylthio)isoindolin-1-one (0509) (0510) 5-Bromoisoindolin-1-one (15 g, 70.74 mmol) and sodium methyl mercaptide (12.40 g, 176.85 mmol) were mixed together in DMF (150 mL) and heated to 100 C. for 1 h. The reaction mixture was cooled to room temperature and poured into water (160 mL). The product extracted with EtOAc (400 mL). The layers were then separated and the aqueous was extracted with EtOAc (3×200 mL). The combined organic extracts were washed with brine (3×100 mL). The organic extracts were combined, dried using a phase separator cartridge and concentrated in vacuo. 5-(Methylthio)isoindolin-1-one (12.00 g, 95%) was obtained as a yellow solid. The material was used in the next step without further purification. (0511) LC/MS: m/z=180 [M-H]-. 1H NMR (500 MHz, DMSO-d6) delta 2.54 (s, 3H), 4.33 (s, 2H), 7.33 (d, 1H), 7.44 (s, 1H), 7.56 (d, 1H), 8.43 (s, 1H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 5-Bromoisoindolin-1-one, other downstream synthetic routes, hurry up and to see.
