Sodium Bicarbonate → HCID 23388249, compound

Participants

Reaction Steps

Acetic acid (0.28 ml)-and 1.6 ml of a 1 M tetrabutylammonium fluoride/THF solution were added to 313 mg of 4-nitrobenzyl (1S,5R,6S)-2-[7-(t-butyldimethylsilyloxy)methyl-5-methylimidazo[5,1-b]thiazol-2-yl]-6-((1R)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate. The mixture was stirred at room temperature for 3.5 hr. The reaction solution was adjusted to pH 7 by the addition of a saturated aqueous sodium hydrogencarbonate solution. The reaction solution was then extracted with ethyl acetate, washed with saturated brine, and dried over magnesium sulfate. The reaction solution was then concentrated under the reduced pressure. The residue was purified by column chromatography to give 279 mg of 4-nitrobenzyl (1S,5R,6S)-6-((1R)-1-hydroxyethyl)-2-(7-hydroxymethyl-5-methylimidazo[5,1-b]thiazol-2-yl)-1-methyl-1-carbapen-2-em-3-carboxylate.
