Procedure

Under nitrogen atmosphere, to a mixture of 0.44 g of 3-hydroxymethyl-1-(2-propynyl)imidazolidine-2,4-dione, 0.58 g of (1R)-trans-3-[(E)-3-ethoxyimino-2-methyl-1-propenyl]-2,2-dimethylcyclopropanecarboxylic acid, catalytic amount of 4-dimethylaminopyridine and 5 ml of anhydrous chloroform was added 0.50 g of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride and the mixture was stirred at room temperature overnight. Thereafter, saturated brine was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over anhydrous magnesium sulfate, then, filtrated, and the filtrate was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to obtain 0.34 g of 2,5-dioxo-3-(2-propynyl)imidazolidin-1-ylmethyl (1R)-trans-3-[(E)-3-ethoxyimino-2-methyl-1-propenyl]-2,2-dimethylcyclopropanecarboxylate (hereinafter, referred to as the present compound (2)) represented by the formula (2):
