Reaction Conditions

Reaction Steps

50 g (1 eq.) tert-butyl 3-(tert-butyldimethylsilyloxy)propylcarbamate dissolved in 200 ml THF were added dropwise to a mixture of 20.7 g (5 eq.) sodium hydride and 300 ml THF at 0° C. After heating the reaction mixture to 10° C., 32.3 ml (3 eq.) methyl iodide were added dropwise. On completion of the addition, the mixture was stirred for 3 h at room temperature. The reaction course was monitored by thin-layer chromatography (30% EtOAc/hexane). Once the conversion was complete, the reaction mixture was quenched with saturated NH4Cl solution and then extracted with ethyl acetate. The combined organic phases were dried over Na2SO4. Following removal of the solvent under reduced pressure, 48 g (92%) of product were obtained in the form of an oil.
