Participants

Procedure

To a solution of 82 mg (0.3 mmol) of 4-bromo-2-[(1-p-tolyl)vinyl]phenol (Compound R) in 3 mL of dichloromethane (under a blanket of argon) was added 0.05 mL (36 mg, 0.34 mmol) of triethylamine followed by 0.3 mL (0.3 mmol) of tert-butyldimethylsilylchloride (1M in dichloromethane). The resultant yellow solution was stirred at ambient temperature overnight (23.7 hours), concentrated in vacuo and purified by flash chromatography (silica, 100% hexane) to give the title compound as a clear, colorless oil.
