実験手順
In a manner analogous to that described for the preparation of sulfinyl imine A2.1 the reaction of 1-(5-bromo-2-fluoro-phenyl)-2,2-difluoro-ethanone (CAS 1262858-97-8; WO2011009943) with (R)-tert-butylsulfinamide yielded the (R)-2-methyl-propane-2-sulfinic acid [1-(5-bromo-2-fluoro-phenyl)-2,2-difluoro-eth-(E)-ylidene]-amide (77% of theory) as a yellow oil. MS (ISP): m/z=356.1 [M+H]+and 358.0 [M+2+H]+.
