To a solution of 4-iodo-6-methoxypyridin-3-amine (Compound 3, 845 mg, 3.4 mmol) in Et3N (12 ml) in a re-sealable pressure tube was added Pd(PPh3)2Cl2 (24 mg, 0.034 mmol), CuI (7.0 mg, 0.034 mmol), and 3-methyl-1-butyne (0.66 ml, 6.8 mmol). The mixture was stirred at room temperature for 20 h and the solvent was removed in vacuo. The residue was purified by chromatography on silica gel (0→30% EtOAc-hexanes) to yield the title compound as beige solid.
