Reference of 6292-59-7,Some common heterocyclic compound, 6292-59-7, name is 4-(tert-Butyl)benzenesulfonamide, molecular formula is C10H15NO2S, 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: 2.2 General procedure: 4-methyl-N-phenylbenzenesulfonamide (3a) A 25 mL oven-dried reaction vessel was charged with Pd(TFA)2 (2.3 mg, 0.01 mmol), 1,10-phenanthroline (3.6 mg, 0.02 mmol), p-toluene sulfonamide (1a, 34.2 mg, 0.2 mmol), cyclohexanone (2a, 32 muL, 0.3 mmol). The reaction vessel was flushed with oxygen three times and then sealed. Toluene (0.7 mL) was added by syringe and the resulting solution was stirred at 140 ¡ãC for 40 h. After cooling to room temperature, the volatiles were removed under vacuum and the residue was purified by column chromatography (silica gel, petroleum ether/ethyl acetate = 4:1) to give the corresponding product 3a (39.9 mg) as white solid in 81percent yield.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 4-(tert-Butyl)benzenesulfonamide, its application will become more common.
