Intermediate 121: tert-Butyl 4-(3-hvdroxypropyr)piperazine-l -carboxylate A mixture of tert-butyl piperazine-1 -carboxylate (2.75 g, 14.8 mmol), l-bromo-3- propanol (1.43 mL, 16.2 mmol) and potassium carbonate (2.25 mL, 27.5 mmol) in acetonitrile (75 mL) was heated at 950C for 4 hours. The solvent was removed under reduced pressure, and the residue was taken up in dichloromethane (300 mL) and washed with water, brine, EPO dried over sodium sulfate and concentrated under reduced pressure. Chromatography on silica gel with methanol in dichloromethane (0-10%) gave a tan solid 2.88 g (80% yield). MS (ESV 245 (MH+) for C12H24N2O3,1H-NMR TCDCl1) delta: 1.44 (m, 9H); 1.70-1.82 (m, 2H); 2.40-2.53 (m, 2H); 2.62-2.65 (m, 2H); 3.43-3.50 (m, 4H); 2.77 (m, 2H); 3.73-3.82 (m, 2H).

57260-71-6 tert-Butyl piperazine-1-carboxylate 143452, apiperazines compound, is more and more widely used in various fields.
