Reaction Steps

To a solution of the (3-dimethylaminopropyl)-ethyl-carbamic acid benzyl ester trifluoroacetate (0.84 g, 2.2 mmol) in ethanol (30 mL) and concentrated hydrochloric acid (0.5 mL, 6 mmol) was added palladium on carbon (10%, 50 mg). The suspension was shaken under 50 psi hydrogen. When the consumption of hydrogen was observed to have ceased, the mixture was filtered through a pad of diatomaceous earth and then concentrated under reduced pressure to give N′-ethyl-N,N-dimethylpropane-1,3-diamine dihydrochloride (400 mg, 89%) as a white solid. MS (ES+): m/z (M+H)=131.3 To a suspension of the N′-ethyl-N,N-dimethylpropane-1,3-diamine dihydrochloride (0.26 g, 1.3 mmol) in dichloromethane (5 mL) was added triethylamine (0.51 mL, 3.9 mmol). After stirring for 10 minutes, the mixture was treated with 17-hydroxywortmannin (0.28 g, 0.65 mmol). After stirring overnight at room temperature, the mixture was concentrated under reduced pressure and then purified by reverse-phase HPLC (employing a gradient elution of 5% acetonitrile/95% water to 95% acetonitrile over 45 minutes). The title compound was obtained as a rust-colored solid (11.6 mg). MS (ES+): m/z (M+H)=561.4.
