Reaction Steps

1-Prop-2-yn-1-ylpiperazine diTFA salt (704 mg, 2 mmol), (prepared as described for the starting material in Example 26), was dissolved in acetonitrile (5 ml). Potassium carbonate (1.38 g, 10 mmol) and 3-bromopropan-1-ol (180 μL, 2 mmol) were added and the mixture heated to 85° C. for 6.5 hours. The reaction mixture was cooled, filtered and concentrated to give an oil. This was triturated with diethyl ether to give a white solid, which was partitioned between dichloromethane and water. The organic phase was then dried (MgSO4) and concentrated to give 3-(4-prop-2-yn-1-ylpiperazin-1-yl)propan-1-ol (286 mg, 79%).
