Reaction Steps

TMS-acetylene (Aldrich) (5.0 mL, 35.5 mmol), ethyl 4-bromobenzoate (58 mL, 35.5 mmol) and Et3N (20 mL, 144 mmol) were combined in 50 mL CH3CN in a glass pressure tube. (Ph3P)2PdCl2 (198 mg, 0.28 mmol) and CuI (100 mg, 0.53 mmol) were added, and the reaction was sealed and heated at 100° for 18 h. Dilution with EtOAc, washing twice with water, then brine, drying and concentration provided 29-1 as a brown liquid.
