Sodium Hydroxide → HCID 57947864, compound

Participants

Reaction Steps

To a solution of (S)-4-(tert-butoxycarbonyl(methyl)amino)-5-(tert-butyldimethylsilyloxy)pentyl acetate (0.124 mol) in THF (200 mL) and MeOH (50 mL) was added sodium hydroxide (2 N, 93 mL, 0.186 mol) at RT The reaction was stirred at RT for 2 h and LC-MS indicated the reaction was completed. The reaction mixture was diluted with EtOAc and the organic layer was washed with water and brine, dried over Na2SO4, filtered, and concentrated. The resulting residue was purified on silica gel column using a mixture of hexanes and EtOAc to give (S)-tert-butyl 1-(tert-butyldimethylsilyloxy)-5-hydroxypentan-2-yl(methyl)carbamate (37.9 g, 88%). LRMS (M+H+-Boc) m/z 248.2.
