실험 절차

A 0° C. mixture of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (5.03 g, 23 mmol) and 1-isocyanato-3-methylbenzene (2.95 mL, 23 mmol) in THF (90 mL) was stirred at room temperature for 1 hour, concentrated, suspended in acetonitrile, and filtered. The filter cake was dried to provide 8.09 g of the desired product.
