Abstract
PURPOSE: To obtain the titled compound useful as medicines, etc., at a low cost, by the reaction of methylglyoxal and/or its acetal with water and/or an alcohol, in the presence of a compound of a specific metal selected from groups IIIb, IVa, Va, etc. in the periodic table, as a catalyst.
CONSTITUTION: Methylglyoxal and/or its acetal is reacted with water and/or an alcohol, preferably at 40°C or above and 300°C or below, in the presence of one or more compounds of a metal selected from groups IIIb, IVa, IVb, Va, VIb, and VII in the periodic table, e.g. Al, In, Tl, Ti, Zr, Sn, Nb, or Cr, as a catalyst in an amount of 0.05wt% or more, preferably 0.1wt% or more based on the methylglyoxal and/or its acetal, to give the titled compound.
