To tert-butyl 2-iodo-6-methoxyphenylcarbamate (10.36 g, 29.67 mmol), ethynyltrimethylsilane (3.20 g, 32.63 mmol), copper(I) iodide (0.28 g, 1.48 mmol), and PdCl2(PPh3)2 (1.04 g, 1.48 mmol) in THF (100 mL) was added triethylamine (3.60 g, 35.6 mmol), followed by overnight stirring. The crude reaction was then concentrated and the mixture was flashed through silica gel with 10:1 Hex/EtOAc to give the desired product (98%).
