Procedure

1-[1-(4-Aminomethylphenethyl)piperidin-4-yl]indoline (0.6 g) was dissolved in tetrahydrofuran (9.0 ml). Under ice cooling, acetyl chloride (0.14 ml) was added dropwise thereinto and the resultant mixture was stirred for 2 hr. After adding a saturated aqueous solution of sodium bicarbonate, the mixture was extracted with ethyl acetate, washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by Cromatorex NH silica gel column chromatography (hexane/ethyl acetate system) to give the title compound (0.518 g) as a pale yellow oil (yield: 79.2%).
