3-Bromopiperidin-2-one 51-1 (0.15 g, 0.87 mmol) was dissolved in n-butanol (4 mL) then triethyl amine (0.26 g, 2.60 mmol) was added followed by tert-butyl piperazine-1-carboxylate 12-1 (0.16 g, 0.87 mmol). This was then stirred at 150° C. for 1.5 hours and then the solid was filtered off, washed with n-butanol and then ethyl ether. Hi-Res MS: calc: 284.1969 found: 284.1966. 1H-NMR (CDCl3): 3.45 (br s, 2H); 3.26 (br s, 2H); 3.13 (complex, 3H); 2.74(m, 1H); 2.62(m, 1H); 1.98(m, 1H); 1.77(m, 1H); 1.55(complex, 3H); 1.45(t, 9H).
