| Reactant | 1,2,4-Benzenetriol | HCID 10787 | — |
| Reactant | Triethyl orthoacetate | HCID 66221 | — |
| Solvent | Toluene carbon tetrachloride | HCID 69067533 | — |
| Product | 2-Ethoxy-5-hydroxy-2-methyl-1,3-dioxolane | HCID 20037280 | 114.1% |
Reaction Steps
A solution composed of 5.0 g of 1,2,4-trihydroxybenzene, 9.7 g of triethyl orthoacetate and 50 ml of toluene-carbon tetrachloride (1:1) was refluxed for 1.5 hours. The solvent was evaporated, and the residue was purified by column chromatography to give 6.7 g (yield 86%) of the desired product as pale brown crystals having a melting point of 86° to 87° C.
