Reaction Steps

A mixture of 2,5-dimethoxybenzaldehyde (2.504 g.) and hydantoin (1.507 g., 1 molar ratio) in water (15 ml) was heated to 70°. To this 2 layer liquid was added monoethanolamine (1.38 g., 1.5 molar ratio). The mixture was heated 4 hours at 90°-92° (bath temperature) with magnetic stirring. The title compound was isolated in the usual manner and obtained as a yellow solid (3.288 g.), m.p. 250°-252°. Crystallization from dioxane (86% recovery) gave m.p. 251°-252°.
