Reaction Steps

To a mixture of (R)-N-[8-(piperazin-1-yl)-1,2,3,4-tetrahydro-2-naphthyl]acetamide (100 mg, 0.37 mmol), potassium carbonate (76 mg, 0.54 mmol) and potassium iodide (15 mg, 0.10 mmol) in acetone (20 mL) was added ethyl bromide (56 μL, 0.74 mmol) added and the reaction mixture was vigorously stirred over night. The reaction was filtered and the solvent was evaporated in vacuo. The residue was purified on a silica gel column using chloroform/methanol/concentrated ammonium hydroxide (95:5:0.5) as the eluent. This gave 87 mg (78% yield) of the title compound as an oil which was crystallized from ethyl acetate/hexane. Yield: 55 mg (50%) as white crystals: mp 142-143° C.; [α]21D +27° (c 0.50, chloroform); EIMS (70 eV) m/z (relative intensity) 301 (100, M+).
