実験手順: A suspension of 4-benzyloxy-2,3-dimethyl-phenol (960 mg), 1-methanesulfonyloxymethyl-cyclopropanecarboxylic acid ethyl ester, prepared as in Step 1 (890 mg) and cesium carbonate (1.5 g) in DMF (20 mL) was stirred at 130 ° C for 6 h, and the mixture was partitioned between EtOAc and water. The organic layer was washed with water, dried over MgSO4 and evaporated. The residue was purified by silica gel column eluting with 10% EtOAc in hexane to give 0.78 g of 1-(4-benzyloxy-2,3-dimethyl-phenoxymethyl)-cyclopropanecarboxylic acid ethyl ester as a clear oil. the mixture was partitioned between EtOAc and water The organic layer was washed with water dried over MgSO4 evaporated The residue was purified by silica gel column eluting with 10% EtOAc in hexane

実験手順: A mixture of 2,3-dimethyl-1,4-dihydroquinone (5 g) and benzyl bromide (6.2 g) and K2CO3 (10 g) in DMF (50 mL) was stirred at 120° C. for 5 h. The mixture was poured into water and extracted with EtOAc. The EtOAc was washed with water, dried and evaporated. The residue was purified by silica gel column eluting with 10% EtOAc in hexane to give 3.2 g of 4-benzyloxy-2,3-dimethyl-phenol as a pale solid. extracted with EtOAc The EtOAc was washed with water dried evaporated The residue was purified by silica gel column eluting with 10% EtOAc in hexane
