Reaction Steps

To a solution of the product of step 1 (49 g, 0.2076 moles) in methanol (343 ml), hydroxylamine hydrochloride (28.6 g, 0.4152 moles) and a solution of sodium acetate (34 g, 0.4152 moles) in water (147 ml) were added and the reaction mixture was refluxed for 1 hour. The solvents were evaporated under reduced pressure. The residue was dissolved in water and extracted with ethyl acetate. The combined ethyl acetate extract was washed with water & brine, dried over sodium sulphate and evapourated under reduced pressure to yield 40 gm (76%) of product as solid.
