Procedure

A mixture of o-methoxybenzaldehyde (2.00 g., 14.7 mmoles) and hydantoin (1.47 g., 1 molar ratio) in water (12ml) was heated to 70°; monoethanolamine (1.35 g., 1.5 molar ratio) was then added. The mixture was heated in an oil bath (90°-92°) and stirred magnetically for 4 hours. Usual workup gave the title compound as an orange solid (2.90 g.), m.p. 174°-179° .
