実験手順: 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. heated to reflux the precipitate is filtered off rinsed successively with water (3×), ethanol (2×), and ether (2×) dried Recrystallization from methanol

実験手順: Vanillin (3.04 g.) and hydantoin (2.0 g.) in water (20 ml were heated on the steam-bath for a few minutes until dissolution occurred. Ethanolamine (0174 g.) was then added and the solution heated at 85°-90° (bath temperature) for 4.5 hours. The solution deposited crystals and solidified within 0.5 hours. Concentrated HCl (5 ml) was added, the mixture was refrigerated overnight (18 hours), filtered, water washed and dried. The title compound was obtained as a yellow solid (4.18 g; 93%), m.p. 266°-271° decomp. the solution heated at 85°-90° (bath temperature) for 4.5 hours the mixture was refrigerated overnight (18 hours), filtered water washed dried
