Procedure

In a 25 mL flask was placed 1-methyl-piperazine (0.52 g, 5.1 mmol), 4-bromobutyronitrile (0.78 g, 5.3 mmol) and potassium carbonate (0.71 g, 5.3 mmol) suspended in acetonitrile (5 mL). The reaction mixture was stirred at rt for 4 h., followed by addition of H2O (20 mL) and extraction with ethyl acetate (3×25 mL). The combined organic phases were washed with brine (25 mL), dried (MgSO4) and evaporated to dryness to produce 0.72 g of crude 14 which was used without further purification in the synthesis of compound 15.
