Reaction Steps

2-amino-5-[1-(indol-3-yl)ethyl]-2-oxazolin-4-one (100 mg) was dissolved into pyridine (0.5 ml). Acetic anhydride (117 μl) was added. The mixture was stirred for 2 hours at 80° C. To the reaction mixture was added water. The mixture was made acidic using 4N hydrochloric acid. The whole was extracted with ethyl acetate. The extract was washed with brine and dried over magnesium sulfate. Concentration of the solution gave a residue, which was subjected to the silica gel chromatography. The eluent with hexane-acetone (1:1) was collected and concentrated to provide the titled compound (16 mg).
