Procedure
Sodium hydride (0.59 g., 0.025 mole) is suspended in benzene (20 ml.) and dimethylformamide (35 ml.). N-(4-acetoxynonyl)methanesulfonamide [Example 1, Step B] (6.1 g., 0.022 mole) is added and stirred 1 hour at room temperature. Ethyl m-bromomethylcinnamate (6.68 g., 0.025 mole) is added dropwise with stirring over 1 hour. The suspension is stirred at room temperature for 20 hours and then separated between ethyl acetate and water. After being washed with water, the organic layer is dried over anhydrous magnesium sulfate. Removal of the ethyl acetate by evaporation in vacuo gives an oil which, after chromatograpy on silica gel, gives ethyl m-[N-(4-acetoxynonyl)-methanesulfonamidomethyl]cinnamate, 4.1 g. (40% yield). Anal. Calcd. for C24H37NO6S: C, 61.64; H, 7.98; N, 3.00 Found: C, 61.36; H, 8.40; N, 3.07
