Reaction Steps
To a solution of 5-bromo-3-(1-methyl-2-(S)-pyrrolidinylmethoxy)-pyridine (816 mg, 3.00 mmol), bis(triphenylphosphine)palladium(II) chloride (42 mg, 0.06 mmol) and copper (I) iodide (10 mg, 0.06 mmol) in CH2Cl2 (6.0 mL) and NEt3 (2.0 mL) was added 5-cyanohexyne (0.481 mL, 4.5 mmol). The mixture was refluxed overnight then cooled to room temperature. Water (4 mL) was added, and solid sodium bicarbonate was added until the aqueous layer was saturated. The mixture was extracted with EtOAc, which was dried over MgSO4, filtered and concentrated. The residue was chromatographed on a silica gel column, eluting with NH4OH/MeOH/EtOAc 0:1:9 and 1:10:90 to afford a light yellowish oil (674 mg, 79%). MS (CI/NH3) m/z 284 (M+H)+. 1H NMR (CDCl3, 300 MHz) δ 1.66-2.10 (m, 6H), 2.26-2.87 (m, 1H), 2.48 (s, 3H), 2.54-2.71 (m, 6H), 3.08-3.16 (m, 1H), 3.89-4.03 (m, 2H), 7.20 (dd, J=3.0 Hz, J=2.1 Hz, 1H), 8.23 (d, J=2.1 Hz, 1H), 8.24 (d, J=3.0 Hz, 1H).
