Reaction Steps

A solution of 7-chloro-3-{6-[1-hydroxy-1-cyclopentyl]pyridin-2-ylmethyl}-3H-[1,2,3]triazolo[4,5-d]pyrimidin-5-ylamine (0.5 g, 1.5 mmol) in dry THF (15 mL) at room temperature was treated with trimethylsilyl chloride (0.38 mL, 3.0 mmol) then triethylamine (0.42 mL, 3.0 mmol), stirred at 35° C. overnight, treated with additional quantities of trimethylsilyl chloride (0.19 mL, 1.5 mmol) then triethylamine (0.21 mL, 1.5 mmol) and stirred at 35° C. for 24 h. The mixture was poured into water (60 mL), extracted with EtOAc (×2), concentrated in vacuo and purified by chromatography (SiO2: isohexane—EtOAc (3:1)) to give the title compound (0.55 g, 88%); NMR δH (400 MHz, DMSO) 7.78 (1H, t, J 7.8 Hz), 7.59 (2H, br s), 7.43 (1H, d, J 7.8 Hz), 7.19 (1H, d, J 7.8 Hz), 5.79 (2H, s), 1.68 (7H, m), 1.40 (2H, m), −0.11 (9H, s); (M+H)+ 418.
