Reaction Steps

3-(Triphenylmethylamino)-4-(3-p-fluorophenylprop-2-ynylthio)azetidin-2-one (1.02g) and t-butyl glyoxalate (2.76g) were refluxed in dry benzene (50ml) with provision for the removal of water. After 1 hour the benzene solution was washed 5 times with water, dried and evaporated. The residue was chromatographed on silica to give 1-(1-Hydroxy-1-t-butyoxycarbonylmethyl)-3-(triphenylmethylamino)-4-(3-p-fluorophenylprop-2-ynylthio)azetidin-2-one as an amorphous solid (0.969g). νmax (CHCl3) 1770, 1735 cm-1.
