Formic Acid → HCID 54180109, compound

Participants

Reaction Steps

19.96 g (156 mmol) of the obtained 2-propynyl 2-hydroxypropionate, 7.17 g (156 mmol) of formic acid, and 15.23 g (125 mmol) of 4,4-dimethylaminopyridine (nucleating agent) were dissolved in 100 g of 1,2-dichloroethane (solvent), and a mixed solution of 35.35 g (171 mmol) of N,N′-dicyclohexylcarbodiimide (dehydrating agent) and 50 g of 1,2-dichloroethane was added thereto at 10° C., taking 30 minutes. These were reacted at room temperature for 4 hours, and the absence of the starting materials was confirmed through gas chromatography. Subsequently, the reaction liquid was filtered to remove N,N′-dicyclohexylurea, and the filtrate was concentrated. The concentrate was purified through silica gel column chromatography, and from the fraction taken with hexane/ethyl acetate=4/1, 20.78 g (yield 85%) of 2-propynyl 2-(formyloxy)propionate was obtained.
