Adding a certain compound to certain chemical reactions, such as: 56341-37-8, name is 6-Chlorooxindole, 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 56341-37-8, SDS of cas: 56341-37-8
Step 1: Synthesis of 2.6-dichloro-1H-indole (2):1003131 To a stirred solution of 6-chloroindolin-2-one 1(500 mg, 2.99 mmol) in toluene (25 mL) under inert atmosphere were added N,N-dimethylaniline (362 mg, 2.99 mmol) and POC13 (918 g, 5.98 mmol) at RT; heated to 110 C and stirred for 1 h. The reaction was monitored by TLC; after completion of the reaction, the reaction mixture was quenched with 10% aq. NaHCO3 solution (30 mL) and extracted with EtOAc (2 x 30 mL). The combined organic extracts were dried over Na2SO4, filtered and concentrated under reduced pressure to obtain the crude. This was purified by silica gel column chromatography using 5% EtOAc/ Hexanes to afford compound 2 (350 mg, 63%) as an off-white solid. 1H NMR (400 MHz, CDC13): 5 8.09 (br s, 1H), 7.41 (d, J= 8.4 Hz, 1H), 7.28 (s, 1H), 7.09 (d, J= 8.4 Hz, 1H), 6.39 (s, 1H); MS (ES): m/z184 (M – Hj
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, 6-Chlorooxindole, other downstream synthetic routes, hurry up and to see.
