18% | With potassium carbonate; In dimethylsulfoxide-d6; at 130℃; for 16h; | To a solution of 1- (4-trifluoromethyl- pyridin-2-yl)-piperazine (233) (500mg, 2.16 mmol) in DMSO were added 4-fluoro-benzoic acid ter-butyl ester (466 mg, 2.37 mmol) (234) and K2CO3 (1.2 g, 11.3 mmol). The mixture was heated for 16 h at 130C, cooled, filtered and concentrated in vacuo. The residue was purified by flash chromatography (eluent AcOEt-hexane from 40: 60 to pure AcOEt) to afford the title compound 244 (162 mg, 18 % yield). LRMS: (calcd.) 406.4 : (found) 407.4 (MH) +. |

82% | With triethylamine; In 1-methyl-pyrrolidin-2-one; at 180℃; for 0.416667h; | 1-(5-Trifluoromethyl-pyridin-2-yl)-piperazine (10 g, 43.3 mmol) is combined with <strong>[34584-69-5]3,6-dichloro-4,5-dimethyl-pyridazine</strong> (14.4 g, 84.3 mmol), triethylamine (8.25 mL), and NMP (40 mL). The reaction mixture is heated to a temperature of 180° C. for 25 min, and then concentrated in vacuo. The residue is purified by flash chromatography on silica gel (0-8percent MeOH/CH2Cl2) to afford the title compound (13.2 g, 82percent). 1H NMR (400 MHz, DMSO-d6) delta=8.48-8.41 (m, 1H) 7.84 (dd, J=9.1 Hz, 2.4 Hz, 1H) 7.03 (d, J=9.1 Hz, 1H) 3.88-3.76 (m, 4H) 3.28-3.20 (m, 4H) 2.31 (s, 6H). |
