DEFINITION Alitame is prepared by a multistep synthesis involving the reaction between two intermediates, (S)-[2,5-dioxo-(4-thiazolidine)] acetic acid and (R)-2-aminoN-(2,2,4,4-tetramethyl-3-thietanyl)propanamide. The final product is isolated and purified through crystallization of an alitame / 4-methylbenzenesulfonic acid adduct followed by additional purification steps, and finally recrystallization from water as the 2.5 hydrate.
