Reaction Steps
A mixture of 2.04 g (6.54 mmol) of 6-bromo-4,4-dipropylthiochroman (Compound 29), 0.12 g(0.64 mmol) of copper (I) iodide and 5.4 g (54 mmol) of triethylamine was degassed using argon for 15 minutes at -78° C. To the suspension was added 1.95 g (19.8 mmol) of (trimethylsilyl)acetylene then 0.41 g (58 mmol) of bis(triphenylphosphine)palladium (II) chloride. The solution was degassed with argon for an additional 5 minutes and the resulting mixture was allowed to warm to 0° C. The tube was sealed and the mixture heated to 55° C. for 15 hours.
