Abstract
PURPOSE: To obtain the titled compound useful as an intermediate for an antiviral agent, agricultural chemical, drug, or a raw material for an amino acid, etc. ion high purity in high yield, by using a mixed catalyst of a monoalkanolamine and an alkali metal hydroxide, and condensing hydantoin with an aldehyde.
CONSTITUTION: In preparing an unsaturated hydantoin shown by the formula by reacting hydantoin with an aldehyde shown by the formula RCHO (R is 1W20C straight-chain or branched-chain aliphatic hydrocarbon group or aromatic hydrocarbon group), a mixed solvent consisting of 0.01W0.5mol, preferably 0.05W0.2mol based on hydantoin of a monoalkanolamine (e.g., monoethanolamine, etc.) and 0.005W0.5mol, preferably 0.02W0.2mol alkali metal hydroxide(sodium hydroxide, etc.) is used as a catalyst.
EFFECT: An amount of a monoalkanolamine used is reduced and treatment with a mineral acid is not required.
USE: An intermediate for food additive.
