Participants

Reaction Steps

A solution of sodium hydroxide (2.70 g, 0.0674 mole) in water (110 ml) was added to 1-(3,5-difluorobenzyl)-2-mercaptoimidazole-5-carboxylic acid methyl ester (6.39 g, 0.0225 mole) and the resulting solution was stirred for 2 hours. The solution was cooled in ice, acidified to pH 2 with 3N hydrochloric acid and the product was filtered and dried. The product was recrystallized from ethanol-water and dried to give a solid melting at 240°-241° C. (5.66 g, 93%).
