Reaction Steps

To 2-(3-methoxyphenyl)-2-methylpropanoic acid (330 mg, 1.70 mmol) and triethylamine (191 mg, 1.87 mmol) in t-BuOH (15 ml), DPPA (514 mg, 1.87 mmol) was added and the resultant solution was refluxed for 2 h. Then t-BuOH was removed under vacuum. Crude residue was dissolved in THF (10 ml) and 2N HCl (10 ml) was added and stirred overnight at RT. Then solvent was removed, crude residue dissolved in water and extracted with ether. Aqueous layer was basified with 5N NaOH and extracted with ethyl acetate. Organic layer was dried and evaporated to yield 2-(3-methoxyphenyl)propan-2-amine.
