実験手順
3-Hydroxy-isophthalic acid di-tert-butyl ester (90 mg, 0.3 mmol) was dissolved in dry acetone (5 ml), K2CO3 (90 mg, 0.65 mmol) and methyl 10-bromodecanoate (0.075 ml, 0.3 mmol) was added. The mixture was heated to reflux. The heating caused dissolution of the K2CO3. After a while, a precipitate was formed. Reflux (50° C.) was continued over night. More K2CO3 (30 mg, 0.2 mmol) and methyl 10-bromodecanoate (0.025 ml, 0.1 mmol) was added. The mixture was refluxed at 50° C. over night. To the dry reaction mixture EtOAc and water was added. After extraction, the organic layer was washed with water and brine, dried (Na2SO4) and concentrated to give the crude title compound as a clear oil.
