Reaction Conditions:
Stage #1: 2-chloropyridinewith MnCl2(THF)1.6 in tetrahydrofuran at 21; for 0.0833333 h;Glovebox;Inert atmosphere;Kumada Cross-Coupling;
Stage #2: n-hexylmagnesium chloride in tetrahydrofuran at 21; for 24 h;Glovebox;Inert atmosphere;Kumada Cross-Coupling;
Steps:
D. General Procedure for Mn-catalyzed cross-coupling of halopyridines
General procedure: 20 mL scintillation vial was charged with a solution of MnCl2THF1.6 (3 mol%, 3 mg, 0.012mmol) in 3 mL THF in a glove box. The corresponding electrophile (0.41 mmol, 1 equiv.) andinternal standard, mesitylene (0.41 mmol, 1equiv.), were added. After five minutes of stirring atroom temperature, the Grignard solution (1.2- 2.6 equiv.) was added dropwise and the reactionwas stirred at room temperature. The reaction mixture was removed from the glovebox andquenched with a saturated K2CO3 solution (3 mL) and EtOAc (3 mL). The organic layer wasextracted with EtOAc (3 x 3mL), and dried over MgSO4. The solution was then filtered andconcentrated. The crude product was purified via a silica plug.
