Mode opératoire

To a solution of dimethyl(2S,3S,5S)-5-(3-fluorophenoxy)-2-[(4-phenylpiperazin-1-yl)carbonyl]piperidine-1,3-dicarboxylate (27 mg, 0.000054 mol) in methanol (0.2189 mL, 0.005405 mol) was added 1.640 M of N-hydroxyamine in Methanol (0.659 mL) made from the corresponding HCl salt and sodium methoxide. After stirred at rt for 1 h, the mixture was acidified with 1N HCl. The resultant mixture was applied directly on RP-HPLC to afford the product as a TFA salt (18 mg 54.5%). MS (ESI): (M+H)+=501.2.
