実験手順

3-(4-[(3-Chloro-4-fluorophenyl)amino]carbonyl-1,2,5-oxadiazol-3-yl)propyl methane-sulfonate (19 mg, 0.051 mmol) was dissolved in anhydrous ACN (100 μL) followed by the addition of DIPEA (44 μL, 0.26 mmol) and morpholine (6.7 μL, 76.8 μmol). The reaction were stirred and heated at 70° C. for 3 h. The reaction was concentrated and purified by silica gel chromatography (60-100% ethyl acetate/hexanes) to give the desired product (10.2 mg, 54%). LCMS for C16H19ClFN4O3 (M+H)+ m/z=369.1.
