Reaction Steps
A mixture of 0.338 g (1.47 mmol) of 4,4-dipropylthiochroman-6-yl)acetylene (Compound 31), 24 mg, (0.13 mmol) of copper (I) iodide, and 2.54 g (25 mmol of triethylamine were degassed with argon for 15 minutes. To the suspension was added 0.57 g (2.07 mmol) of ethyl 4-iodobenzoate (Compound 22) and then 0.12 g (0.17 mmol) of bis(triphenylphosphine)palladium (II) chloride. The suspension was degassed with argon for an additional 5 minutes, the tube was sealed and the mixture stirred at 55° C. for 16 hours.
