Reaction Steps
Add n-BuLi (48.2 mL, 77.1 mmol, 1.6N in hexane) to a −70° C. solution of diisopropylamine (10.8 mL, 77.1 mmol) in THF (130 mL) in a flame-dried flask. After 30 minutes add 3-bromo-pyridine (2.48 mL, 25.7 mmol) dropwise and stir the mixture at −70° C. After 4 hours, add 2-chloro-benzaldehyde (2.95 mL, 26.2 mmol) dropwise, stir at −70° C. After 1 hour, warm reaction to RT, quench reaction with dropwise addition of 60 mL saturated NH4Cl solution. Extract with Et2O (3×), wash with brine, dry the combined organic layers over MgSO4 and concentrate. Purify the residue by flash chromatography on silica gel eluting with 0-40% EtOAc/hexane to afford the title compound: MS(IS) 299 (M+1); TLC (50% EtOAc/hexanes) Rf=0.23.
