Reaction Steps

To a stirred solution of 6-chloro-4-(4-fluorophenyl)-3-trifluoromethyl-pyridazine (D7) (0.81 g, 2.93 mmol) and N-Boc-piperazine (0.818 g, 4.39 mmol) in acetonitrile (10 ml) was added diisopropylethylamine (1 ml, 5.9 mmol) and the mixture was stirred at 80° C. for 30 min., under microwave irradiation. After this period, the reaction mixture was diluted with dichloromethane and extracted with water. The organic layer was separated, dried (MgSO4) and the solvents evaporated in vacuo to yield D8 (1.27 g, 62%) C20H22F4N4O2 requires 426; Found 427 (MH+).
