反応手順
A mixture of p-methoxybenzaldehyde (2.00 g., 14.7 mmoles) and hydantoin (1.47 g., 1 molar ratio) in water (12 ml) was heated to 70°; monoethanolamine (1.35 g., 1.5 molar ratio) was then added. The mixture was stirred magnetically and heated in an oil bath at 90°-92° for 4 hours. Usual workup furnished the title compound as a pale yellow solid (2.74 g.), m.p. 250°-252°.
