Reaction information

*#Reaction file  
*Reaction file type CDX
*Procedure   General procedure A with 4-Methyl-N-(4-phenylbut-3-yn-1-yl)benzenesulfonamide (1.50 g, 5.0 mmol) and (Bromoethynyl)benzene (996 mg, 5.5 mmol).  Purification by column chromatography (SiO2, hexane/Et2O 4:1) gave the title compound as an orange oil (1.20 g, 60%).


General procedure A: 

A solution of the appropriate sulfonamide (1 eq.) and the appropriate bromide (1.1 eq.) in DMF (35 mL) was added to K2CO3 (2 eq.), CuSO4.5H2O (0.1 eq.) and 1,10-phenanthroline (0.2 eq.).  The reaction mixture was stirred at 65 °C for 16 h.  The reaction mixture was poured into water (200 mL) and extracted with ether (3 × 50 mL).  The organic extracts were combined, washed with water (2 × 100 mL), dried (MgSO4), filtered and the solvent removed in vacuo to give the crude product, which was purified as described.

*Yield (%)  60
*Type of Yield Isolated product yield
