Sodium Bicarbonate → HCID 15117238, compound

Participants

Reaction Steps

To a solution of (3S,4R)-4-[2-(1-benzyloxycarbonyl-1,2,3,6-tetrahydropyridin-4-yl)-2-oxoethyl]-3-[(1R)-1-t-butyldimethylsilyloxyethyl]-2-oxoazetidine (4.65 g) in acetonitrile (25 ml) was added dropwise boron trifluoride ether complex (2.6 ml) at 0° C., and the mixture was stirred for 1 hour. Sodium hydrogen carbonate (5 g) was added to the reaction mixture, followed by stirring for 30 minutes, and then precipitate was filtered off. Filtrate was dissolved in ethyl acetate (100 ml), washed in turn with water (50 ml) and brine (50 ml), dried over magnesium sulfate. Evaporation of the solvent in vacuo gave (3S,4R)-4-[2-(1-benzyloxycarbonyl-1,2,3,6-tetrahydropyridin-4-yl)-2-oxoethyl]-3-[(1R)-1-hydroxyethyl]-2-oxoazetidine (3.6 g).
