A suspension of (5-amino-7-(2-furyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-yl)acetic acid (140 mg, 0.5 mmol) in DMF (1 mL) was treated with carbonyl diimidazole (81 mg, 0.5 mmol), stirred at room temperature for 1 h, treated with 3-chloroaniline (53 μL, 0.5 mmol) and the mixture heated to 50° C. for 16 h. The reaction mixture was cooled, diluted with water (3 mL) and filtered to give the title compound (94 mg, 48%) as a cream solid.
