2-Ethynyl toluene (456 μL, 3.62 mmol) was added to 1,1,1-tributyl-N,N-dimethylstannanamine (1.21 g, 3.62 mmol), and the mixture was stirred in a sealed vial at 70° C. for 3 hours. The mixture was cooled to ambient temperature, and the vial was stirred unsealed for 10 minutes. Benzyl azide (678 μL, 5.42 mmol) was added, and the vial was resealed and heated to 130° C. overnight. The mixture was purified by silica gel chromatography eluting with a gradient of 5-45% ethyl acetate in hexanes to afford the title compound. MS (ESI+) m/z 539.8 (M+H)+.
