Reaction Steps

To a stirred solution of N-(5-benzyloxy-6-hydroxymethyl-4-oxo-4H-pyran-2-ylmethyl)-benzene sulfonamide (10-01) (2.8 g, 6.98 mmol) in ethyl acetate (100 mL) IBX (2-iodoxy benzoic acid) (5.86 gm, 20.95 mmol) was added and the reaction mixture was heated up to 60° C. for 6 h. After completion of the reaction, the reaction mixture was filtered and concentrated to get the crude compound. It was then purified using normal column chromatography to get N-(5-benzyloxy-6-formyl-4-oxo-4H-pyran-2-ylmethyl)-benzene sulfonamide (11-01) (2.0 g, 71.71%) as a gummy liquid.
