Reaction Steps
3-Bromopropan-1-ol (581 mg, 4.18 mmol) and potassium carbonate (2.88 g, 20.9 mmol) were added to a solution of 1-(2-fluoroethyl)-piperazine diTFA salt (1.5 g, 4.18 mmol) in acetonitrile (11 ml). The reaction mixture was stirred at 85° C. for 4 hours and then loaded directly onto a column and eluted with a mixture of methanol in methylene chloride (7/93) to give 3-[4-(2-fluoroethyl)piperazin-1-yl]propan-1-ol (721 mg, 91%). NMR Spectrum: (CDCl3) 1.72 (m, 2H); 2.58(m, 8H) 2.62 (m, 2H); 2.73 (t, 2H); 3.79 (t, 2H); 4.55 (dt, 2H). MS-EI: 191 [MH]+
