A mixture of prop-2-yn-1-ol (0.22 g, 3.85 mmol) and (S)—N-(1-azido-3,3-dimethylbutan-2-yl)-2-chloro-5-fluoropyrimidin-4-amine, 216a, (0.21 g, 0.77 mmol) in THF (4 mL) and toluene (4 mL) was heated in a pressure vial at 120° C. for 8 hours. The reaction mixture was cooled to room temperature and concentrated under reduced pressure. The crude product which contained two regioisomers was purified by silica gel chromatography (0-5% MeOH/CH2Cl2 gradient) to afford 100 mg of desired regioisomer, 217a, as well as 70 mg of the minor regioisomer (5-hydroxymethyl triazole).
