Reaction Steps

7-Acetamido-8-benzyl-5,6,7,8-tetrahydronaphthalen-2-yl trifluoromethanesulfonate (100 mg, 0.234 mmol; prepared in analogy to 8-(3,4-dichlorobenzyl)-7-[(ethoxycarbonyl)amino]-5,6,7,8-tetrahydronaphthalen-2-yl trifluoromethanesulfonate, example 29), N-(prop-2-ynyl)propane-1-sulfonamide (75 mg, 0.468 mmol), palladium tetrakistriphenylphosphine (54 mg, 0.047 mmol), copper(I) iodide (35.6 mg, 0.187 mmol) and triethylamine (65 μL, 0.468 mmol) in dioxane (3 mL) were heated under reflux for 16 h. Water (15 mL) was added and the mixture extracted with dichloromethane (3×20 mL). The combined organic extracts were dried (MgSO4) and the solvent was evaporated in vacuo. The crude product was purified by flash chromatography (silica gel, dichloromethane, methanol). Yield: 56 mg (0.132 mmol, 57%).
