Reaction Steps

1-[4-((1R,2S,3R)-1,2,3,4-Tetrahydroxy-butyl)-1H-imidazol-2-yl]-ethanone (172 mg, 0.74 mmol) was suspended in ethanol (4 ml) and water (1 ml). 4-fluorobenzoic acid hydrazide (131 mg, 0.85 mmol, 1.1 eq.) and hydrochloric acid (one drop, 12 N) were added, and the suspension was stirred at 55° C. for 48 hours. LCMS analysis indicated the formation of the product and the absence of starting material. The reaction mixture was cooled to room temperature, and partially concentrated in vacuo. The resulting white precipitate was collected and washed with ethanol to yield the product, as one apparent isomer, as a white solid: 97 mg (35%).
