Reaction Steps
0.37 gram (1.3 mmole, 1.0 eq.) of product from step E was dissolved in 5 ml of dichloromethane. The solution was stirred under nitrogen atmosphere at -78° C. and 3.2 ml of 1.0 M boron tribromide solution in hexanes (3.2 mmole, 2.5 eq.) was added dropwise over a 5-8 minute span. The reaction was allowed to slowly warm, and after 3 hours ice was added to the reaction mixture. After an additional 30 minutes some water was added and the mixture was diluted with dichloromethane. The layers were separated and the organic was washed twice more with water, dried over sodium sulfate, filtered and evaporated to give the title compound (0.33 gram, 100% yield) without further purification.
