実験手順

A solution of N-methyl-2,2,2-trifluoroacetamide (197 mg, 1.55 mmol) in DMF (5 mL) at 0° C. was treated with sodium hydride (60% dispersion in mineral oil; 62 mg, 1.55 mmol), stirred for 15 min, treated with 3-(6-bromomethyl-2-pyridylmethyl)-7-(2-furyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine-5-amine (120 mg, 0.310 mmol), stirred at 50° C. for 1 h, cooled to room temperature, poured into water (20 mL), extracted with EtOAc (3×10 mL) and the combined organic phase dried (MgSO4) and concentrated in vacuo to give N-(6-(5-amino-7-(2-furyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-3-ylmethyl)-2-pyridylmethyl)-N-methyltrifluoroacetamide. A solution of this product in MeOH (20 mL) was treated with a solution of sodium (71 mg, 3.10 mmol) in MeOH (10 mL), stirred for 16 h, concentrated in vacuo, treated with EtOAc (20 mL), filtered through Celite and concentrated in vacuo. The resulting solid was suspended in MeOH (2 mL), treated with HCl (4-M in dioxane, 1.0 mL), stirred for 10 min, concentrated in vacuo and triturated with Et2O to give the title compound (80 mg, 58%) as a yellow solid.
