Procedure
Compound 1 (100 mg) was dissolved in acetonitrile, and the resultant solution was subjected to photoreaction by use of a high-pressure mercury lamp. The resultant reaction mixture was concentrated to dryness under reduced pressure, followed by purification by use of a silica gel column, to thereby produce the target product (41 mg, yield: 41%).
