Versuchsvorschrift

tert-Butyllithium (1.040 mL, 1.77 mmol) was added dropwise to THF (5 mL) at −100° C. under an argon atmosphere. A solution of 6-bromo-3-methoxy-2,4-dimethylpyridine (191 mg, 0.88 mmol) in THF (3 ml) was added dropwise followed by the addition of (E)-N-((3-bromophenyl)(2-cyano-3-fluorophenyl)methylene)-2-methylpropane-2-sulfinamide (300 mg, 0.74 mmol) in THF (7 ml). The resulting reaction mixture was left on the thawing cooling bath for 30 min then the cooling bath was removed and the mixture was stirred at r.t. for 1 h. Hydrogen chloride-methanol solution (3.54 mL, 4.42 mmol) was added and the resulting mixture was stirred at r.t. for 1 h. The mixture was concentrated under reduced pressure and the residue was purified on a silica gel column eluted with 0-10% 0.1 M NH3 in MeOH in DCM to give the title compound (272 mg, 84%). MS (ES+) m/z 440, 442 [M+1]+.
