To a solution of (3S,5S,6S)-5-(methoxycarbonyl)-1-methyl-6-[(4-phenyl-3,6-dihydropyridin-1(2H)-yl)carbonyl]piperidin-3-ylpiperidine-1-carboxylate (94 mg, 0.00020 mol) in methanol (0.8109 mL, 0.02002 mol) was added 1.640 M of N-hydroxyamine in methanol (2.44 mL) made from the corresponding 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 (56 mg, 48%). MS (ESI): (M+H)+=471.1.
