実験手順
Prepared from 5-(difluoromethoxy)picolinic acid (69.7 mg, 369 μmol, Eq: 1.00) and (R)-5-(5-amino-2-fluoro-phenyl)-5-methyl-1,1-dioxo-1,2,5,6-tetrahydro-1λ6-[1,4]thiazin-3-ylamine (100 mg, 369 μmol, Eq: 1.00) as described for example 2 (method b) to give the title compound (85 mg, 192 μmol, 52.1% yield) as a white foam. MS (ISP): m/z=443.4 [(M+H)].
