A series of 10-benzyl-9-acridones were synthesized and their reduction with NaBH4 to 10-benzy1-9,10-dihydroacridine derivatives was developed. Acridone 1 reacted with benzyl chlorides 2 in NaH/DMF/KI to give 10-benzyl-9-acridones 3 in high yields. Subsequent reduction of 3 with NaBH4 gave 10-benzy1-9,10-dihydroacridine derivatives 4 with yields of 88%~96%. However, the expected 10-benzy1-9,10-dihydro-9-hydroxyacridine derivatives 4’ were not detected. Probably, 4’ is the first reduc-tion product, which is not stable and reduced to 4 by NaBH4 immediately.

Key words: acridone, 9,10-dihydroacridine, NaBH4, acridine
