Reaction Steps

Methyl 3,3-dimethyl-4-oxobutanoate (10 g, 70 mmol), prepared according to the procedure of Hudlicky et al., Synth. Commun., 16 169 (1986), was dissolved in 40 mL of benzene, followed by addition of ethylene glycol (20 mL), and p-toluenesulfonic acid monohydrate (1.3 g). The reaction was refluxed with azeotropic removal of water for 1 hour.
