Reaction Steps

To 51 mg (0.19 mmol) of (5-Chloro-2-nitro-phenyl)-(1-methyl-[1,2,3]triazol4-yl)-methanone in 2 ml of methanol were added 0.05 ml of 12M HCl and 200 mg (0.89 mmol) of stannous (II) chloride monohydrate, and the mixture was heated at 100° C. for four hours. The mixture was then cooled to ambient temperature, partitioned between 1M NaOH and ethyl acetate, and the phases were separated. The ethyl acetate phase was washed once each with water and brine, dried over Na2SO4, filtered, and concentrated in vacuo to a solid. The solid was chromatographed to give the title product as a yellow solid.
