Procedure

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, 2.52 g (8.41 mmol) of n-octadecyl isocyanate (98% Aldrich) was added dropwise. Within seconds, a yellow precipitate formed. Chloroform (20 ml) was added to aid stirring. The precipitate was filtered to remove the reaction liquid, then washed with 20 ml of chloroform resulting in a pale yellow powder (3.38 g, 96.0% crude yield, mp=109° C.).
