Reaction Steps

3-bromopyridine (1 g, 6.329 mmol) was reacted with cylcobutanone (0.93 mL, 6.369 mmol), n-butyl lithium (4.02 mL, 7.64 mmol) and diisopropyl amine (0.99 mL, 7.005 mmol) in dry THF to afford the crude product. Purification by column chromatography on silica gel (40% ethyl acetate in hexane) afforded 802 mg of the product (55% yield). LCMS Purity: 79%, m/z=227.9 (M+1)
