Reaktionsschritte

In 4 ml of ethanol was dissolved 440 mg (1.3 mmol) of 5-(3,5-dichlorophenylthio)-4-isopropyl-1-methyl-1H-imidazole-2-carbaldehyde (Compound I-6), followed by addition of 51 mg (1.3 mmol) of sodium borohydride at room temperature. After 10 minutes, the mixture was neutrized by acetic acid and sodium bicarbonate, and extracted with methylene chloride. The organic layer was washed with water and dried over sodium sulfate. The solvent was then concentrated under reduced pressure and the residue was recrystallized by isopropyl ether:n-hexane to provide 340 mg (yield 77%) of Compound I-8. mp 157 to 158° C.
