Reaction Steps
A solution of ethyl 2-(3,4-dimethoxyphenyl)-2-methylpropanoate (2.84 g, 11.26 mmol) and hydrazine hydrate (7.00 mL, 112.56 mmol) in MeOH (15 mL) was heated at 110° C. in a sealed tube. After 12 h, additional hydrazine hydrate (10 mL) was added to the reaction mixture, which then was heated for additional 6 h. The cooled mixture was concentrated to afford 2-(3,4-dimethoxyphenyl)-2-methylpropanehydrazide (2.75 g, quant) as a liquid. 1H NMR (400 MHz, CDCl3) δ 6.94-6.91 (m, 1H), 6.87-6.81 (m, 2H), 3.88 (s, 3H), 3.87 (s, 3H), 3.69 (br s, 3H), 1.56 (s, 6H).
