---|---|---|
To a solution of 3-nitrosalicyclic acid (500 mg, 2.73 mmol) in dichloromethane (10 mL) is added oxalylchloride (2 M in dichloromethane, 1.50 ml, 3 mmol) and three drops of N,N-dimethylformamide. The mixture is stirred at room temperature overnight. The solvent is evaporated under vacuum to leave a crude residue, a portion of which (127 mg, 0.63 mmol) is dissolved in dichloromethane (5 mL) and the solution cooled to 0 C. Triethylamine (0.22 mL, 1.57 mmol) is added followed by <strong>[832710-65-3]2,8-diaza-spiro[4.5]decan-1-one hydrochloride</strong> (100 mg, 0.52 mmol). The mixture is allowed to warm to room temperature and stirred overnight. Water is added, the phases separated, the organic layer dried over MgSO4 and evaporated under reduced pressure to give compound 1-1.Yield: 200 mgES mass spectrum: [M+H]+=320Retention time: 0.69 min (HPLC method 2) |
