Adding a certain compound to certain chemical reactions, such as: 3984-14-3, name is N,N-Dimethylsulfamide, belongs to amides-buliding-blocks 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 3984-14-3, COA of Formula: C2H8N2O2S
To a solution of 4-((5-chloro-6-fluoropyridin-3-yl)oxy)-2,5-difluorobenzoic acid (Preparation 19, 490 mg, 1 .62 mmole) in DCM (100 mL) was added N,N- dimethylsulfamide (Preparation 29, 241 mg, 1 .94 mmol), followed by addition of HOBt (2 mg, 120 umol), DMAP (237 mg, 1 .94 mmol) and EDCI (31 1 mg, 1 .62 mmol). The reaction mixture was stirred at 30 C for 16 hours. The solvent was removed in vacuo then 2M HCI (20 mL) was added and extracted with EtOAc (3x 15 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo to afford the title compound (570 mg, 86%) that was used directly in library protocol 1 . 1 H NMR (400 MHz, DMSO) delta ppm 2.85 (s, 6H), 7.35 (s, 1 H), 7.75 (s, 1 H), 8.20 (s, 1 H), 8.25 (s, 1 H), 1 1 .95 (s, 1 H). LCMS Rt 2.82 min MS m/z 408 [M-H]”
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, N,N-Dimethylsulfamide, other downstream synthetic routes, hurry up and to see.
