Reaction Steps

A mixture of 4-isopropylbenzoic acid (10 g) and sulfuric acid (5 mL) in methanol (50 mL) was heated under reflux overnight, hydrazine monohydrate (3.66 g) was added, and the mixture was heated under reflux 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 aqueous sodium hydrogen carbonate solution and saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give the title compound (10.32 g) as a yellow oil.
