Participants

Reaction Conditions

Reaction Steps

To a solution of 1-(4-fluorophenyl)-2-mercapto-N-methoxy-N-methyl-1H-imidazole-5-carboxamide (8) (1 g, 3.55 mmol) in anhydrous THF (71 mL) at 0° C. was added lithium aluminum hydride (2M in THF, 5.3 mL, 10.65 mmol). The reaction was stirred at 0° C. for 1 h and for an additional 3 h at room temperature. The reaction was quenched at 0° C. with 15% sodium bicarbonate (40 mL) and water (40 mL) and extracted with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel (0-100% EtOAc in hexanes) to afford 1-(4-fluorophenyl)-2-mercapto-1H-imidazole-5-carbaldehyde (12).
