実験手順

6-Cyclopropylmethoxy-[1,2,4]triazolo[4,3-b]pyridazin-3-ylamine (W1.009; 350 mg) was initially charged in DMF (5 ml) at RT while stirring, and 2-bromo-1-(3-tert-butyl-4-methoxy-5-morpholin-4-ylphenyl)ethanone (O1.003; 631 mg) predissolved in DMF (5 ml) was added dropwise. The reaction mixture was stirred at RT for 14 h. Then the solvent was removed under reduced pressure and the residue was purified using silica gel (40 g cartridge, dichloromethane/ethanol gradient of 0-40% in 60 min). The product was taken up with a little acetonitrile, diluted with water and, after addition of 2 eq. of HCl, freeze-dried. 500 mg of the title compound were obtained. LC-MS rt: 1.37 min [M+H]+: 495.2 (met. a)
