A solution of 2,4-dibromopyrimidine (50 mg, 0.210 mmol) and 1-(tetrahydro-2H-pyran-4-yl)piperazine, 2 Hydrochloride (51.1 mg, 0.210 mmol) in Ethanol (1 mL) was treated with DIPEA (0.147 mL, 0.841 mmol) and DMAP (cat.) and stirred at ambient temperature for 1 h. The reaction mixture was concentrated in vacuo and triturated with water, filtered and the solid washed with water then dried in vacuo to provide 2-bromo-4-(4-(tetrahydro-2H-pyran-4-yl)piperazin-1-yl)pyrimidine (43 mg, 0.130 mmol, 61.9% yield) as an off-white solid. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 1.54 (s, 2H) 1.73 (br. s., 2H) 2.48 (br. s., 1H) 2.61 (br. s., 4H) 3.38 (t, J=11.24 Hz, 2H) 3.65 (br. s., 4H) 4.02 (br. s., 2H) 6.40 (d, J=6.25 Hz, 1H) 7.95 (d, J=5.86 Hz, 1H). LC/MS (m/z) ES+=327 (M+1).
