[0222] To a solution of 2-chloro-5-iodopyridine in THF was added isopropyl magnesium chloride (0.5 ml, 2N in diethyl ether) at -78 C. The mixture was warmed up to RT for a couple hours to complete iodide-magnesium exchange and re-cooled to -78 C. when Intermediate from Preparative Example 2 was added to the reaction mixture. The resulting solution was stirred at RT for 16 h and quenched with 1N NaOH, exacted with EtOAc. The organic layer was washed with brine, dried over magnesium sulfate and evaporated under vacuum.
