실험 절차

1.22 g (3.61 mmol) of ethyl 4-amino-1-methyl-1H-imidazole-2-carboxylate (synthesis analogous to Example 4A, stage 3, or else according to Tetrahedron Lett. 2003, 44, 1607 and literature cited therein) in 50 ml of THF are mixed with 1.46 g (7.21 mmol) of 4-(trifluoromethoxy)phenyl isocyanate under argon and stirred at room temperature overnight. The reaction mixture is filtered, and the filtrate is concentrated in vacuo and purified by chromatography.
