Reaction Conditions

Reaction Steps

To a solution of 2-cyclopropylacetaldehyde (1.00 g, 11.89 mmol, purchased from Beta Pharma, Inc., Branford, Conn.) in THF (15 mL) at 0° C. under N2 was added 2-pyridylmagnesium bromide (47.6 mL×0.25 M, purchased from Rieke Metals, Inc., Lincoln, Nebr.) dropwise over 15 min. The mixture was stirred at 0° C. after 30 min, allowed to warm to rt and stirred at rt for 3.5 hr. To the reaction mixture was added saturated aqueous NH4Cl solution (5 mL) followed by water (15 mL). The mixture was extracted with EtOAc (2×10 mL). The combined organic layers were dried over Na2SO4. After removal of organic solvents, purification of the residue by flash chromatography on silica gel with 40-70% EtOAc/hexanes the title compound was obtained as a white solid. Mass Spectrum (ESI) m/z=164.1 (M+1).
