Participants

Reaction Steps

The above ester (12.0 g, 33 mmol) was reacted with 30% H2O2 (50 ml) in glacial acetic acid (350 ml) at 55° C. for 24 h. The mixture was cooled and 600 ml of icecold water was added. The precipitate was filtered off and recrystallized from DMF-water to afford 7.16 g of the title compound. M.p. 286°-289° C. 1H-NMR(DMSO-d6):δ5.08(s, 2H), 5.22(s, 2H), 7.28-7.45(m, 6H), 7.75(s, 1H), 12.35(s, 1H).
