Reaction Steps
To a solution of Boc-protected triazole from Example 3 (4.344 g, 12 mmol) in 20 mL of THF at −60° C. under argon was slowly added a solution of n-butyl lithium (1.6M) in hexane (7.5 mL, 1.2 eq.) and stirred at −60° C. for 30 minutes. To the mixture was added a suspension of N-chlorosuccinimide (4.67 g, 2.9 eq.) in 20 mL of THF and the mixture was kept at −60° C. for 1 hr before warming up to RT overnight. The reaction mixture was treated with sat. aqueous NaHCO3 (30 mL), then extracted with EtOAc (2×40 mL). The organic phase was dried over Na2SO4 and concentrated in vacuo. Flash chromatography purification ((Hex/EtOAc) provided the desired product (1.011 g, 21.2%).
