Category: 672-58-2

Reference of 672-58-2,Some common heterocyclic compound, 672-58-2, name is 3-(Trifluoromethyl)benzenesulfonamide, molecular formula is C7H6F3NO2S, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

General procedure: In 25ml RB flask to a solution of Compound 9 (200 mg) in dry DMF (5ml), EDCI (250 mg, 1.25eq) and DMAP (130 mg,1eq) were added followed by addition of Sulfonamide (1eq). RM was stirred at RT for 4hrs. Solvent from the reaction mixture was evaporated. To the residue water was added and acidified with 6N HCl, solid precipitated out. Solid was filtered and dried. Crude solid was purified by flash chromatography eluating with 4-8% MeOH/DCM as solvent system to give pure product.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3-(Trifluoromethyl)benzenesulfonamide, its application will become more common.

Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 672-58-2, name is 3-(Trifluoromethyl)benzenesulfonamide, This compound has unique chemical properties. The synthetic route is as follows., COA of Formula: C7H6F3NO2S

General procedure: To a stirred solution of glucal (1 equiv.) and N-nucleophile (1.1 equiv.) inanhydrous 1,2-dichloroethanne (2 mL/mmol) under an atmosphere of argon was added Zn(OTf)2 (10 mol%) at 40?C. The reaction mixture was stirred untilthe complete consumption of the starting material (glycal). The solvent wasfiltered and concentrated in vacuo, and the crude residue was redissolved indichloromethane and loaded on a silica gel column. The product was purified by silica gel column chromatography using hexane/EtOAc as the eluent to affordthe 2,3-unsaturated N-glycosides. All of the products were confirmed by1H NMR, 13C NMR, and MS/HRMS spectroscopy and compared with that of literature data; characterization data of new products are outlined in the experimentalsection

According to the analysis of related databases, 672-58-2, the application of this compound in the production field has become more and more popular.
