Reaction Steps

A mixture of 3,5-dimethoxybenzaldehyde (2.550 g.) and hydantoin (1.505 g., 1 molar ratio) in water (15 ml) was heated to 70°. Monoethanolamine (1.38 g., 1.5 molar ratio) was added and the 2 layer liquid mixture was magnetically stirred at 90°-92° (bath temperature) for 4 hours. Isolation in the usual manner gave the title compound as a beige solid (2.870 g.), m.p. 285°-287°.
