16.5 g | i) To a solution of tert-butyl N-(4-bromophenyl)carbamate (20.1 g) in dry THF (400 mL) at -78C under nitrogenatmosphere was added dropwise n-BuLi (59.1 mL, 2.5 M in hexanes). After stirring at -78C for 2 hours, dicyclopropylmethanone(9.28 mL) was added dropwise and the reaction mixture was allowed to slowly warm up to RTovernight. The reaction mixture was quenched by addition of a saturated aqueous NH4Cl solution (200 mL). Thelayers were separated and the aqueous layer was extracted with EtOAc (2x200 mL). The combined organic extractswere washed with brine, dried over Na2SO4 and concentrated under reduced pressure. The residue was purifiedby column chromatography on silica gel, using DCM as the eluent to obtain 16.5 g of tert-butyl N-[4-[dicyclopropyl(hydroxy)methyl]phenyl]carbamate. |
