Versuchsvorschrift

To a mixture of 0.50 g of the product of Example 7, excess triethylamine, and ethyl acetate at room temperature was added 0.25 g p-toluene sulfonyl chloride and this was allowed to sit 3 days at room temperature. The reaction mixture was then washed with H3PO4, NaHCO3, and NaCl solutions, dried over MgSO4, filtered, and stripped to an oil. This oil was purified by chromatography on silica gel (70-230 mesh) using 1/1 hexane/EtoAc as eluant. The product was obtained as a viscous oil. 0.28 g (42%). NMR (CDCl3) δ 0.88 (3H, z), δ 1.26 (24H, m), δ 1.66 (2H, m), δ 2.01 (4H, m), δ 2.44 (3H, s), δ 3.21 (2H, m), δ 3.79-3.88 (9H, m), δ 5.34 (2H, m), δ 6.15 (2H, s), δ 7.26-7.75 (5H, m). IR (KBr) 3019, 2925, 1599, 1466, 1206 cm-1.
