Abstract
NEW MATERIAL:A hydantoin derivative shown by the formulaI(x and Y are 2W 5C alkoxycarbonyl, acetyl, cyano, or benzoyl; R2 is 1W4C alkyl, 1W4C alkoxy, or halogen; n is 0W3).
EXAMPLE: 5-Di(ethoxycarbonyl)methylene-3-phenylhydatoin.
USE: An intermediate for an agricultural chemical and a drug.
PROCESS: An α,β-unsaturated-α-amino aicd ester, e.g., 1-amino-1,2,2-triethoxy- carbonylethylene, etc. shown by the fomula II (R1 is 1W4C alkyl) is reacted with an aromatic isocyanate, e.g., phenyl-isocyanate, etc. shown by the formula III in the presence of a tertiary amine, e.g., triethylamine, etc. under substantially anhydrous conditions in a solvent, preferably benzene, etc. at 20W100°C for 0.5W 100hr, to give a compound shown by the formulaI.
