Reaction Steps
A solution of tert-butyl 3-((2-bromo-5-chlorophenyl)carbamoyl)azetidine-1-carboxylate 7.56 (400 mg, 1.03 mmol) in THF (3 mL) was cooled 0° C. Sodium hydride (60%, 63 mg, 1.58 mmol) was added and mixture stirred at 0° C. for 15 minutes. Iodomethane (0.45 mL, 7.23 mmol) was then added dropwise and the mixture was warmed to rt and stirred overnight. Reaction mixture was quenched with water and taken up in EtOAc. Layers were separated, and aqueous was extracted with ethyl acetate. Combined organics were washed with brine, dried (Na2SO4), filtered, concentrated under reduced pressure. The resulting residue was purified via silica gel column chromatography (0-35% ethyl acetate/hexanes) to yield tert-butyl 3-((2-bromo-5-chlorophenyl)(methyl)carbamoyl)azetidine-1-carboxylate 7.57 (393 mg). LCMS-ESI+ (m/z): [M+H]+ calcd for C16H21BrClN2O3: 402.03; found: 402.75.
