Reaction Steps
3-(Triphenylmethylamino)-4-(3-phenylprop-2-ynylthio) azetidin-2-one (526mg) and methyl glyoxylate (1.17g) were refluxed in dry benzene (25ml) with provision for the removal of water. After 11/2 hours the solvent was evaporated and the residue was chromatographed on silica to give 1-(1-hydroxy-1-methoxycarbonylmethyl)-3-(triphenyl methylamino)-4-(3-phenylprop-2-ynylthio)azetidin-2-one as an amorphous solid (399 mg).
