Reaction Steps

A mixture of 4-hydroxy-3-methoxybenzaldehyde (4.6 g, 30 mmoles), 1-methyl hydantoin (3.5 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 8 hours the mixture is stirred into water (300 ml) and the precipitate filtered off, rinsed successively with water (3X), ethanol (2X), and ether (2X), and dried. Recrystallization from acetonitrile gave the pure product (1.1 g), mp 197°-198° C.
