Adipic Acid → HCID 136333635, compound

Participants

Reaction Steps

To 500 mg of guanosine in anhydrous pyridine was added adipic acid (5 mol eq) and bis(2-oxo-3-oxazolidinyl)phosphinic chloride (BOPDC) (1.0 mol eq.). The mixture was allowed to stir at room temperature for 18 h, then the solvent was removed in vacuo. The residue was added to 100 mL of ice-cooled water and the aqueous layer adjusted to pH 3.0 and then extracted three times with 60 mL of ethyl acetate. The combined extracts are dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue was chromatographed on a silica gel column and eluted with a mixture of chloroform-ethanol, whereupon the eluate was evaporated in vacuo.
