Procedure

In a manner analogous to that described for the preparation of sulfinyl imine E2.1 the reaction of 2-fluoro-1-(2-fluoro-phenyl)-ethanone with (R)-tert-butylsulfinamide yielded the (R)-2-methyl-propane-2-sulfinic acid [2-fluoro-1-(2-fluoro-phenyl)-eth-(E)-ylidene]-amide (62% yield) as an orange oil. MS (ISP): m/z=260.2 [M+H]+.
