Procedure

Following a procedure similar to that described in Example 3c, 5-(2-methyl-1,3-dioxolan-2-yl)-2-[3-(2,6-dimethyl-4-cyanophenoxy)propyl]furan; (1.05 g; 3.08 mmol), 48 mL (0.06M) of dimethyldioxirane in acetone, and 10 mL of acetone were reacted. The resulting product was dissolved in methanol and reacted with 85% hydrazine hydrate (0.15 mL; 4.49 mmol) then purified by chromatography on silica gel with 65% ethyl acetate/hexane to afford 0.511 g (47%) of 6-(2-methyl-1,3-dioxolan-2-yl)-3-[3-(2,6-dimethyl-4-cyanophenoxy)propyl]-pyridazine.
