Reaction Steps

According to the second and third steps of the present invention, 3,3-dimethylbutyraldehyde is added to the mixture and reacted with aspartame in the presence of the catalyst and in the presence of hydrogen for a time and at a temperature sufficient to produce neotame. 3,3-Dimethylbutyraldehyde can be added slowly or all at once to the reaction mixture. When the aldehyde is gradually added, typically it is added over the course of about 2 to 8 hours, preferably from about 4 to 6 hours. It is important to note that the reactants, i.e., aspartame, catalyst, aldehyde, can be added in any order.
