Reaction Steps

To a solution of nitroethane (0.0952 ml, 1.33 mmol) in benzene (2 mL) was added phenyl isocyanate (0.291 ml, 2.66 mmol). The solution was stirred at 50° C. for ten minutes followed by the addition of triethylamine (0.00925 ml, 0.0666 mmol) and tributyl(ethynyl)stannane (0.365 ml, 1.27 mmol). The mixture was left to stir at 50° C. overnight. The solution was diluted with water and filtered though a celite plug, the resulting filtrate was extracted with toluene. Organic extracts were dried over magnesium sulfate and filtered then concentrated to yield the product as a yellow oil.
