1.00 g (8.40 mmol) of p-aminostyrene (99% Tokyo Kasei) was added to a 250 ml round bottom flask containing 10 ml of chloroform. After ten minutes of mixing, 1.12 g (8.41 mmol) of o-tolyl isocyanate (99% Aldrich) was added dropwise. Within seconds, a yellow precipitate formed. The precipitate was filtered to remove the reaction liquid, then washed with 20 ml of chloroform resulting in pale yellow powder (1.45 g, 68% crude yield, mp=193° C.).
