Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 138-41-0, name is Carzenide, A new synthetic method of this compound is introduced below., category: amides-buliding-blocks
Step 14-sulfamoylbenzoyl azide (JS129)4-sulfamoylbenzoic acid (1 .00 g, 4.97 mmol), triphenylphosphine (2.61 g, 9.94 mmol) and sodium azide (0.388 g, 5.96 mmol) were suspended in anhydrous acetone (10 ml). To this milky white suspension was added trichloroacetonitrile (0.997 ml, 9.94 mmol) drop wise and the reaction was left to stir at RT for 18 h. The solvent was removed in vacuo and the resulting dark yellow slurry was diluted with CH2CI2 and washed with H20 and brine, dried (MgS04), filtered and concentrated in vacuo. Flash chromatography (Pet Ether; 3:1 to 2:1 to 1 :1 Pet Ether/EtOAc) afforded the title compound as a white solid (906.9 mg, 4.01 mmol, 80.7%). Mpt: 1 18 C; Rf = 0.23 (1 :1 Pet Ether/EtOAc); IR (vmax/cm”1, thin film): 3362 (aromatic C-H stretch), 3258 (N-H stretch), 2137 (N=N=N stretch), 1687 (CO stretch), 1339 (S=0 stretch, asymmetrical), 1238, 1 155 (S=0 Symmetrical stretch); 1H NMR (600 MHz, CD3OD): deltaEta = 8.02 (ap.d, J = 6.9 Hz, 2H, 4-H), 8.18 (ap.d, J = 6.8 Hz, 2H, 3-H); 13C NMR (150 MHz, CD3OD): 5C = 127.6 (C-4), 131.0 (C-3), 134.9 (C-2), 150.2 (C-5), 172.8 (C-1 ); LRMS/HRMS m/z (ES+): no product mass present; Anal. Calcd. for C7H6N403S: C, 37.17; H, 2.67; N, 24.77. Found C, 37.27; H, 2.49; N, 24.40%.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
