Reaction Steps

To a solution of 50 mg (0.116 mmol) 17-hydroxywortmannin in 1 mL CH2Cl2 is added 22.5 mL (0.217 mmol) diethylamine. The reaction mixture is stirred at room temperature for 2 hours 30 minutes and then concentrated in vacuo to give an orange paste. The residue is dissolved in ethyl actate (EtOAc) and precipitated with hexane. The precipitate is washed two times with hexane to give 45 mg (77%) product as an orange solid. HRMS (ESI) m/z calcd for C27 H37NO8 503.25206, found: 504.25747 (M+H)+1.
