実験手順
To a solution of (2,4-dimethylphenyl)(2-methylpropyl)amine (400 mg, 2.256 mmol) in pyridine (5 mL), stirred in air at room temperature, was added 4-formylbenzene-1-sulfonyl chloride (760 mg, 3.71 mmol) in one charge. The reaction mixture was stirred at 20° C. for 30 minutes, then left to stand 6 hours. The solvent was removed in vacuo and the crude material purified by flash (Si) chromatography (using a 0-25% ethyl acetate-cyclohexane gradient). The appropriate fractions were combined and evaporated in vacuo to give the required product (794 mg) as a colourless gum. LCMS (M+1) 346, RT 1.33 mins.
