Reaction Steps

The product from step 9 (36 mg, 0.105 mmole), and hydroxylamine hydrochloride (22 mg, 0.315 mmole) were dissolved in DMF (0.70 ml). To the solution, BOP (49 mg, 0.11 mmole) was added with stirring at r.t. for 10 min. DIEA (61 mg, 0.47 mmole) was added. The mixture was stirred at r.t. for 2 hours. The product was purified with preparative HPLC providing 22 mg of (5S,6S)—N-hydroxy-6-((4-phenylpiperazin-1-yl)carbonyl)spiro(2.5)octane-5-carboxamide. Yield: 44%. MS: M/Z 358.2 (M+H)+; 380.2 (M+Na)+; 737.2 (2M+Na)+.
