実験手順

To a solution of Compound (37) (573 mg, 1.00 mmol) in 60 ml of ethanol were added 306 mg (3.00 mmol) of N-aminomorpholine and 328 μl (3.51 mmol) of trifluoroacetic acid. The reaction was allowed to proceed for 72 hours. The reaction mixture was then concentrated under reduced pressure. The residue was purified by a silica gel column chromatography (silica gel 100 g; n-hexane:ethyl acetate=7:3) to give 265 mg (40%) of Compound (60).
