Reaction Steps

To 1.51 g (9.55 mmol) bromopyridine in 50 mL ether at −20° C. was added 6 mL (1.6 M in hexane, 9.6 mmol) n-butyl lithium, after 10 minutes the mixture was cooled to −78° C. and 1.61 g (8.7 mmol) 3-formyl-azetidine-1-carboxylic acid tert-butyl ester in 20 mL ether was added. The mixture was stirred and allowed to warm to room temperature, quenched with 50 mL 1 M sodium bicarbonate solution and then extracted with 50 mL DCM. The organic layer was dried over Na2SO4. After filtration and evaporation of the solvent the desired product was purified by column chromatography (silica, heptane/EtOAc 1:1 to EtOAc).
