Procedure

A mixture of (3,5-dichloro-6-phenyl-pyridazin-4-yl)-(3-pyridyl)methanone (100 mg, 0.3 mmol) and methyl hydrazine (19.5 mg, 0.42 mmol) in ethanol (1.5 mL) was stirred in a sealed tube at 60° C. for 3 h. The reaction mixture was concentrated in vacuo and the residue was purified by column chromatography (silica gel, isohexane/ethyl acetate 9:1 to 8:2) yielding Compound 26 as a solid (30 mg).
