Reaction Steps

100 mg (298 μmol) 5-ethyl-6-[2-(4-hydroxy-phenyl)-benzoxazol-6-yl]-4,5-dihydro-2H-pyridazin-3-one, 38.5 μL (316 μmol) 2-bromo-1,1-dimethoxy-ethane, 125 mg (904 μmol) potassium carbonate and 3 ml DMF are stirred for 6 h at 150° C. and then at RT over the weekend. Then the mixture is diluted with EA, and extracted with 10% sodium carbonate solution and then with sat. saline solution. The solv. of the org. phase is eliminated i.V. The residue is purified on silica gel (eluant: DCM/methanol) the solv. of the corresponding fractions is eliminated i.V. and the residue is recrystallised with EA/cyclohexane.
