Reaction Steps

The ketone from Step 1 (1.065 g, 5 mmol) and 4-methoxyphenylhydrazine hydrochloride (870 mg, 5 mmol) in toluene (20 is mL) were gently warmed up to 60° C. After 1 h, 4M HCl/dioxane (2 mL) was added and the mixture was heated at 60° C. for 1 h. It was then cooled, poured over ice water and ethyl acetate. The organic layer was separated, washed with dilute NaHCO3. Removal of the solvents left a residue which was purified by chromatography over SiO2 to afford the product (433 mg).
