Reaction Steps

A mixture of methyl 4-(1-methylethyl)benzoate (10 g) and hydrazine monohydrate (5.62 g) in methanol (50 mL) was heated under reflux overnight. To the reaction mixture was added toluene (50 mL), and the mixture was heated at 120° C. overnight. The reaction mixture was added to a saturated aqueous sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was washed with hexane and diisopropyl ether to give the title compound (9.22 g) as a white solid.
