실험 절차
4-Bromo-3,5-dimethylphenol (1.3 g, 6.51 mmol) and NaH (60% on mineral oil: 167 mg, 4.17 mmol) are stirred in 8 mL of N,N-dimethylformamide for 30 min in a microwave vial, methanesulfonic acid 2-methanesulfonyl-2-methyl-propyl ester (600 mg, 2.61 mmol) is added and the reaction mixture is heated in a microwave oven at 160° C. for 2 h. The solvent is removed under vacuum and the crude product is purified by flash chromatography (cyclohexane/ethyl acetate 99/01→90/10) to give the title compound (Yield: 250 mg).
