Versuchsvorschrift

N-(3-methyl-5-isoxazolyl)-5-(2-formylphenyl)thiophene-2-sulfonamide was prepared in the same manner as described in Example 32C from 2-formylbenzeneboronic acid (281 mg, 1.87 mmol) and N-(3-methyl-5-isoxazolyl)-5-bromothiophene-2-sulfonamide (550 mg, 1.7 mmol). Purification by column chromatography using 15% MeOH/CHCl3 gave 63 mg (28%) of the pure sulfonamide as a brown oil.
