1H-Imidazole-2-methanol, 5-((3,5-dichlorophenyl)thio)-4-(1-methylethyl)-1-((2-nitrophenyl)methyl)- → 1H-Imidazole-2-methanol, 1-((2-aminophenyl)methyl)-5-((3,5-dichlorophenyl)thio)-4-(1-methylethyl)-

Participants

Reaction Steps

In ethyl acetate was dissolved 170 mg of 5-(3,5-dichlorophenylthio)-2-hydroxymethyl-4-isopropyl-1-(o-nitrobenzyl)-1H-imidazole (103c), platinum sulfided carbon was added. After replacement with hydrogen atomosphere, catalytic hydrogenation was performed at atmospheric pressure at room temperature. After 1 hour, the mixture was filtered through Celite, and the filtrate was distilled off under reduced pressure To the residue, diethyl ether was added, the precipitated crystals were collected by filtration, and 77 mg of Compound I-119 was obtained (yield 49%).
