Application of 22958-64-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 22958-64-1, name is 2-(4-Sulfamoylphenyl)acetic acid belongs to amides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
[00324] To a solution of 2-amino-5-(cyclohexylmethyl)-6,6-dimethyl-4, 5,6,7- tetrahydrothieno[3,2-c]pyridine-3-carbonitrile Core-1 c_A (1.15 g, 3.8 mmol) in DMF (12 mL) was added 2-(4-sulfamoylphenyl)acetic acid (1.23 g, 5.7 mmol), DIPEA (982 mg, 7.6 mmol) and a solution of T3P in EtOAc (4.84 g, 50% w/w, 7.6 mmol). The mixture was stirred at 65 C for 1 h. The reaction mixture was diluted with water (25 mL) and extracted with EtOAc (15 mLx4). The organic layer was concentrated. The residue was purified by column chromatography on silica (PE:EtOAc=10:1 ~2:1) to afford the desired product (1.15 g, yield 60%) as light yellow solid; LC-MS Rt 1.08 min, MS m/z [M+H]+ 501.3; Method 1 ; 1H NMR (400 MHz, DMSO-cfe) d 1 1.9 (s, 1H), 7.78 (d, J = 8.4 Hz, 2H), 7.48 (d, J = 8.4 Hz, 2H), 7.33 (s, 2H), 3.96 (s, 2H), 3.49 (s, 2H), 2.46 (s, 2H), 2.24 (d, J = 6.8 Hz, 2H), 1.76 – 1.73 (m, 2H), 1.67 – 1.64 (m, 3H), 1.39 – 1.33 (m, 1H), 1.25 – 1.15 (m, 3H), 1.02 (s, 6H), 0.88 – 0.75 (m, 2H).
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, 2-(4-Sulfamoylphenyl)acetic acid, other downstream synthetic routes, hurry up and to see.
