Reaction Steps

1-[4-((1R,2S,3R)-1,2,3,4-Tetrahydroxy-butyl)-1H-imidazol-2-yl]-ethanone (150 mg, 0.65 mmol) was suspended in methanol (3 ml) and water (1 ml). Ethyl carbazate (78 mg, 0.75 mmol, 1.2 eq.) and hydrochloric acid (one drop, 12 N) were added, and the suspension was stirred at 50° C. for 18 hours. LCMS analysis indicated the formation of the product and the absence of starting material. The reaction mixture was cooled to room temperature, concentrated in vacuo, and diluted with acetone. The resulting white precipitate was collected and washed with acetone to yield the product, one apparent isomer, as a white solid: 96 mg (47%).
