Reaktionsschritte

A solution 2.2 g of (4-chloro-phenyl)-{4-[hydroxy-(1-trityl-1H-imidazol-4-yl)-methyl]-1-methyl-1H-pyrrol-2-yl}methanone in 50 mL of CH2Cl2 was stirred with 2.5 g of activated manganese dioxide overnight. The reaction was filtered and the filtrate was evaporated in vacuo to give 2.0 g of (4-chlorophenyl)-[1-methyl-4-(1-trityl-1H-imidazole-4-carbonyl)-1H-pyrrol-2yl]methanone. CI-MS m/z=556 (M++H).
