Reaction Steps
2,2,2-Trifluoroethanol (3 ml) was initially charged at RT and admixed with sodium hydride (403 mg) in portions while cooling with ice. Thereafter, the reaction mixture was heated to 55° C. for 2 h and then 3-methoxy-6-methyl-4-nitropyridazine 1-oxide solution (500 mg, dissolved in 3 ml of 2,2,2-trifluoroethanol) was added dropwise. After stirring at RT for 1 h, the mixture was heated to 55° C. for 2.5 h. After standing at RT overnight, the mixture was admixed with water and DCM. After removing the DCM phase, the aqueous phase was extracted three times with DCM and the combined DCM phases were dried over sodium sulfate, filtered and concentrated. 571 mg of the title compound were obtained.
