Reaction Steps
The product from Example 4 (2.0 g) was slurried in dichloromethane (100 ml) under nitrogen, cooled to -20° C. and boron tribromide (1.3 ml) added. The resultant mixture was stirred at -20° C. for half an hour and then at room temperature overnight. The mixture was poured into ice water, extracted in ethyl acetate and evaporated. The product was recrystallized from acetic acid.Yield: 0,6 g, melting point 162-165° C.
