Procedure:
This procedure is derived from the general method of T. Taguchi, et al. (Tetrahedron Lett., 1986, 27, 6103-6106). Ethyl difluoroiodoacetate (0.355 mL, 651 mg, 2.60 mmol) was added to a rapidly stirred suspension of copper powder (333 mg, 5.24 mmol) in DMSO (6.5 mL) at rt. After 50 min., 3-bromo-6-methylpyridazine (300 mg, 1.73 mmol) was added in DMSO (1.0 mL). After 20 h, the mixture was transferred to a separatory funnel containing water (25 mL) and saturated aq. NH4Cl (25 mL), and extracted with ethyl acetate (2×50 mL). The organic extracts were washed with saturated aq. brine, dried (sodium sulfate), decanted, and evaporated. Purification by flash column chromatography on silica gel, eluting with 70:30 v/v hexanes/ethyl acetate, gave 363 mg of the title compound as an amber liquid. For the title compound:
