Reaction Steps

To a solution of 2,3-dichloro-5-methylfuro[3,2-b]pyridine (0.661 g, 3.27 mmol) (Example 12, Step 2) in 16 mL of THF was added a 1.7M solution of t-butyllithium (4.04 mL, 6.87 mmol). After 30 min the solution was quenched at -78° C. with methanol and a solution of NH4C1. The reaction was brought to room temperature and extracted with EtOAc. The organic solvents were evaporated and the title compound was purified by flash chromatography on silica with EtOAc:hexane 1:4 to yield 0.444 g (81%).
