methyl 4-[[tert-butyl(dimethyl)silyl]oxymethyl]cyclohexane-1-carboxylate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of EXAMPLE 391A (43.6 g) and triethylamine (42.3 mL) in dichloromethane (633 mL) was added tert-butyldimethylsilyl chloride (38.1 g) and 4-dimethylaminopyridine (3.09 g) and the reaction was stirred overnight at room temperature. A saturated solution of aqueous NH4Cl was added and the layers were separated. The organic layer was washed with water and brine, dried (Na2SO4), filtered and concentrated by rotary evaporation. The residue was purified by regular phase flash column chromatography (Analogix, 0-40% hexanes/ethyl acetate. the layers were separated The organic layer was washed with water and brine dried (Na2SO4) filtered concentrated by rotary evaporation The residue was purified by regular phase flash column chromatography (Analogix, 0-40% hexanes/ethyl acetate
