반응 단계

A mixture of 6-Acetylamino-1-(N-methylaminomethyl)indan (1.5 g), 4-cyclohexylbutan-1-ol mesylate (2.5 g), potassium carbonate (1.4 g), and a crystal of potassium iodide in MIBK (80 ml) were refluxed for 5 h. After cooling inorganic salts were filtered off and the solvent evaporated in vacuo. The remaining oil was subjected to column chromatography on SiO2 (eluted with ethyl acetate:heptane:triethylamine 80:20:4). The free base of the title compound was isolated as an oil. The sesquioxalate of 13a crystallized from acetone. Yield 1.6 g Mp: 145°-155° C.
