Participants

Reaction Steps

5-(4-Hydroxymethylphenyl)-2-(4-nitrophenyl)-N-(2-thiazolyl)imidazole-4-carboxamide (2.67 g) obtained in Example 93 was dissolved in tetrahydrofuran (300 ml) and triphenylphosphine (3.33 g) and N-chlorosuccinimide (1.70 g) were added. The mixture was stirred for 15 min and triphenylphosphine (3.33 g) and N-chlorosuccinimide (1.70 g) were added. The mixture was stirred for 30 min. The reaction mixture was poured into ice water and extracted with ethyl acetate. The ethyl acetate layer was washed with water and, after drying, concentrated. The obtained residue was recrystallized from ethyl acetate to give 5-(4-chloromethylphenyl)-2-(4-nitrophenyl)-N-(2-thiazolyl)imidazole-4-carboxamide (2.60 g), melting point 280° C. or above.
