Reaction Steps

A mixture of Compound 9 (1.7 g, 5.3 mM), as prepared in Example 9, bromopropylchloride (5.3 ml, 5.3 mM) and cesium carbonate (3.5 g, 10.6 mM) in acetone (60 ml) was stirred at reflux for 24 hours then cooled to RT. The acetone was removed under reduced pressure, the residue diluted with water (60 ml) and the aqueous mixture was extracted with ethyl acetate (2×60 ml). The combined ethyl acetate layers were dried over MgSO4 and evaporated in vacuo to give the product (2.1 g, 100%) as an oil that solidified on standing. m/z (MH+) 393.
