실험 절차

6.7 g (0.29 mol) sodium were added to 300 mL EtOH under an argon atmosphere. 60.0 g (0.27 mol) ethyl acetamidomalonate were added to the resulting solution, stirred for 1.5 h and then 62.0 g (0.27 mol) 4-bromomethyl-1,2-diethyl-benzene were slowly added dropwise. The reaction mixture was stirred overnight at RT, poured onto 1 L of water and vigorously stirred for 1 h at RT. The precipitate formed was suction filtered, suspended twice with a little water, suction filtered and dried.
