Reaction Steps

To a solution of methyl 2-(N-cyclohexyl-4-(3-formyl-4-nitrophenyl)oxybutyramidyl)acetate (3.5 g) in dry pyridine (20 ml) under a blanket of nitrogen was added solid tetra-N-butylammonium permanganate portionwise over 1 hour. The reaction was stirred at room temperature for 1 hour and was then poured into ethyl acetate/6M hydrogen chloride (100 ml each). Solid sodium bisulfite was added to decolorize the solution and the layers were separated. The aqueous layer was washed with ethyl acetate (2×50 ml). The combined organic layers were washed with 1M HCl (3×50 ml) and brine (2×50 ml), dried, filtered and evaporated to give a syrup which foamed at high vacuum from dichloromethane to yield methyl 2-(N-cyclohexyl-4-(3-carboxy-4-nitrophenyl)oxybutyramidyl)acetate.
