Abstract
A method for preparing chromogenic .alpha.-amylase substrate compounds at substantially high preparative yields in a relatively short period of time by the transglucosylation of a chromogenic glucoside compound to a maltooligosaccharide chain. The concentration of the maltooligosaccharide compound is greater than about 3 times the concentration of the chromogenic glucoside compound to result in at least about 50% of the chromogenic glucoside compound being converted to the desired chromogenic .alpha.-amylase substrate compound.
