Participants

Reaction Steps

The compound (8.33 g) obtained in (1) above and a 5% sodium hypochlorite solution (380 ml) were stirred with refluxing for 44 hours. The reaction mixture was cooled to room temperature and concentrated hydrochloric acid (10 ml) was dropwise added. The resulting solid was collected by filtration. The obtained solid was subjected to silica gel column chromatography (hexane-ethyl acetate) to give 1.96 g of a red-brown solid (yield 23%).
