Reaction Steps

Commercially available 2-methyl-propane-2-sulfinic acid amide is reacted with commercially available 1,4-dioxa-spiro[4.5]decan-8-one in the presence of a coupling agent such as Ti(OEt)4 or CuSO4, in an organic solvent such as dichloromethane, THF or dioxane, at a temperature in the range of about 25° C. to about 80° C., to yield 2-methyl-propane-2-sulfinic acid (1,4-dioxa-spiro[4.5]dec-8-ylidene)-amide.
