実験手順
A mixture of 20.06 g (0.098 mole) of [(2-chloroethyl)sulfonyl]benzene 15.44 g (0.109 mole) of N-(2-aminoethyl)homopiperidine, and 15.0 g (0.149 mole) of triethylamine in 800 ml of acetonitrile was stirred at room temperature for 18 hr. The solvent was removed in vacuo, and the residue was partitioned between methylene chloride and water. The methylene chloride solution was dried over magnesuim sulfate, and the solvent waas removed in vacuo to give an oil. This was dissolved in methanol, and the solution was treated with a solution of 2 equivalents of maleic acid (25.52 g, 0.22 mole) in methanol. A white solid precipitated at room temperature to give 32.3 g (60.7%) of title compound as a white solid; mp 144°-146° C.
