Reaction Steps
The product from step 2.4 (2.82 g) and the product from step 2.2 (6.0 g) were mixed in diethylamine (44 ml). Copper (I) iodide (0.026 g) and dichloro di(triphenylphosphine) palladium (0) (0.193 g) were then added and the mixture was then stirred at 20° C. under argon for 16 hrs. Purification by chromatography gave 4.3 g of tolane product, mpt. 43° C.
