Reaction Steps

A solution of 7-(5-methyl-2-furyl)-3-(4-nitro-2-pyridylmethyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine-5-amine (60 mg, 0.17 mmol) in EtOH (40 mL), MeOH (20 mL) and water (15 mL) was treated with ammonium chloride (280 mg, 5.23 mmol) and zinc (138 mg, 2.05 mmol), stirred for 1 h, filtered through Celite, concentrated in vacuo to −20 mL, diluted with brine (20 mL), extracted with EtOAc (3×20 mL) and the combined organic phase dried (MgSO4) and concentrated in vacuo to give the title compound (40 mg, 73%) as a yellow solid.
