Reaction Steps

2-(N-Carbethoxyamino)-5,6-dimethoxybenzaldehyde-ethyleneketal (5.0 g, 16.8 mM) is dissolved in acetone (36 ml) and aqueous HCl (3 ml of 1N solution). The mixture is stirred at room temperature for 4 hours. The solvent is removed in vacuo to give a yellow solid (3.9 g). Recrystallization from n-hexane gives the pure product as a yellow solid; yield 3.6 g (84.7%); m.p. 86°-88° C.
