A process for preparing a sucralose-6-ester, a key intermediate to
sucralose. The process contains (a) creating a heterogeneous mixture
comprising a first phase comprising a sucrose-6-ester and a second phase
comprising a chlorinating reagent; and (b) reacting the sucrose-6-ester
with the chlorinating reagent, to prepare a sucralose-6-ester. In
addition, processes for preparing sucralose are provided.
