Reaction Steps
A mixture of 4-hydroxy-3-methoxybenzaldehyde (4.6 g, 30 mmoles), hydantoin (3.0 g, 30 mmoles), β-alanine (1.4 g, 16 mmoles), and acetic acid (40 ml) is stirred under an inert atmosphere and heated to reflux. After 4 hours the mixture is stirred into water (350 ml) and the precipitate is filtered off, rinsed successively with water (3×), ethanol (2×), and ether (2×), and dried. Recrystallization from methanol afforded the pure product (3.0 g), mp 272°-273° C.
