实验步骤: 2,3,4-Trichloro-N-(4-bromo-3-methyl-5-isoxazolyl)benzenesulfonamide was prepared from 5-amino-4-bromo-3-methylisoxazole and 2,3,4-trichlorobenzenesulfonyl chloride according to the procedures described in Example 30. The crude product was purified by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p.110-113° C., yield 66%. The crude product was purified by recrystallization from ethyl acetate/hexanes to give a crystalline solid, m.p.110-113° C., yield 66%

实验步骤: A solution of 2,3,4-trichlorobenzenesulfonyl chloride (15 mg, 0.055 mmol), 5-(3-aminophenyl)tetrazole (8 mg, 0.05 mmol) and dry pyridine (12 μL) in CH2Cl2 (200 μL) was stirred at room temperature over night. The solvent was evaporated and the crude product was purified by preparative HPLC (ACE C8, 5 μm 21×50 mm, flow 25 ml/min, 50 mM NH4OAc in water/CH3CN) to give 13 mg (65%) of the title compound. MS (ESI+) calcd for C13H8Cl3N5O2S 402.946428, found 402.946188. The solvent was evaporated the crude product was purified by preparative HPLC (ACE C8, 5 μm 21×50 mm, flow 25 ml/min, 50 mM NH4OAc in water/CH3CN)
