Reaction Steps

To a solution of 3-bromo-2-(cyclopropylmethoxy)-5-iodopyridine (12.5 g) in dry THF (300 mL) was added i-PrMgCl*LiCl (30 mL, 38.3 mmol) dropwise at 0° C. The mixture was stirred at 0° C. for 20 min and then B(OMe)3 (5.5 g) was added at 0° C. The mixture was allowed to warm to r.t. and stirred for 3 h. The mixture was quenched by the addition of brine (50 mL). The organic phase was separated and the aqueous phase was extracted with EA (50 mL×3). The organic phases were combined and the solvent was removed under reduced pressure. The residue was treated according Typical Procedure 5a to obtain the title compound. MS ESI+: m/z=244 [M+H]+.
