Abstract
Provided is a two-step method of producing a compound of chemical formula 1 in the presence of an alcohol solvent and a Group 3B metal catalyst or a salt thereof, comprising a first step comprising alkylation or isomerization of an aldohexose-containing substrate to obtain an intermediate, and a second step comprising dehydration of the intermediate to produce a compound of chemical formula 1. Preferably, additional solvent and/or catalyst are not added in the second step.
