実験手順

Compound 156 (0.81 g, 1.40 mmol) and hex-5-enyl-methyl-amine hydrochloride (272 mg, 1.82 mmol) was dissolved in dry DMF (50 mL). DIEA (975 μL, 5.6 mmol) was added and the reaction flask was placed in an ice bath. After 10 minutes HATU (559 mg, 1.47 mmol) was added to the solution. The reaction flask was allowed to reach room temperature and the stirring was continued for 3 hrs before the solvent was removed by evaporation. The crude product was extracted with CHCl3 and washed with saturated NaHCO3 (aq). The organic phase was dried (Na2SO4), evaporated on silica and purified to by flash chromatography (heptane:ethyl acetate 1:1) to give the title compound (0.716 g, 76%), LRMS (M+H) 673.
