To a solution of methyl 4-(3-tosyloxypropyl)benzoate (500 mg) in dimethylformamide (3 mL) is added 2M dimethylamine solution in tetrahydrofuran (2.2 mL) and the mixture is stirred at 50° C. for 15 hours. The reaction mixture is diluted with ethyl acetate, washed with a saturated sodium hydrogencarbonate solution and concentrated in vacuo. The residue is purified by column chromatography on silica gel (Solvent; chloroform:methanol=100:0→90:10) to give methyl 4-[3-(dimethylamino)-propyl]benzoate (357 mg, yield; quantitative) as an oil.
