Reaction Steps

To the solution of compound (84) (0.703 mmoles) in ethanol (10 ml) was added hydroxylamine HCl (2.878 mmoels) and pyridine (2.844 mmoles) at ambient temp. The reaction was heated to reflux for 2.0 hrs. After completion of reaction, distilled off the solvent completely, added water (20 ml) and the product was extracted in Ethyl acetate (2×100 ml), washed with 10% brine and dried over sodium sulphate. The solvent was distilled completely under reduced pressure to get the crude compound. This crude compound was purified by preparative HPLC to get the pure isomers (86 & 87).
