Reaction Steps

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of 5-(4-nitro-[1,2,3]triazol-2-ylmethyl)-furan-2-carboxylic acid methyl ester (325 mg, 1.28 mmol) in THF (13.0 mL) was treated dropwise, at −10° C. with DiBAL (4.36 mL of a 1M solution in toluene, 4.36 mmol). The reaction mixture was stirred at −10° C. for 1 h followed by 1 h at rt. Sat. aq. Rochelle's salt (40 mL) was added and the reaction mixture was stirred for 1 h at rt. The aq. layer was extracted with EA (2×30 mL). The combined org. extracts were dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Purification of the residue by FC (50:50 hept-EA) gave the title compound: TLC:rf (50:50 hept-EA)=0.28. LC-MS-conditions 02: tR=0.77 min.
