To a solution of 5-tert-butyl-7-(3,3-difluoropyrrolidin-1-yl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine (41.3 μmol), (S)-1-(2-chlorophenyl)ethanol (12.9 mg, 82.6 μmol) and PPh3 (21.7 mg, 82.6 μmol) in THF (250 μL) was added DEAD (13.1 μL, 82.6 μmol) at 0° C. After being stirred at the room temperature for 2 h, the reaction mixture was directly purified by preparative HPLC (column: Gemini 5 um C18 110A 75×30 mm. mobile phase: water (0.05% Et3N): acetonitrile 50:50% to 5:95%. WL: 300 nm Flow: 30 mL/min.) to afford the title compound as light-yellow gum (3.1 mg, 17%). MS(m/e): 421.4 (MH+).
