Reaction Steps

To a solution of 1-(3-fluoro-4-methoxybenzyl)aminoacetaldehyde dimethyl acetal (6.68 g, 0.0275 mole) in ethyl alcohol (40 ml) was added potassium thiocyanate (2.94 g, 0.0302 mole) in water (65 ml) followed by 12 N hydrochloric acid (6 ml) and the reaction mixture was heated under reflux for 3 hours. The solvent was partially removed under reduced pressure and the mixture was cooled in ice and the product filtered. The product was recrystallized from ethyl alcohol to give 1-(3-fluoro4-methoxybenzyl)-2-mercaptoimidazole as a solid melting at 156-157° (3.98 g, 61%).
