Reaction Steps
A solution of N-benzyl-α-(R)-methylbenzylamine (0.82 g, 3.87 mmol) in THF (25 mL) at 0° C. was treated with n-BuLi (1.6 mL of a 2.5 M soln in hexanes). The resulting solution was stirred at 0° C. for 30 min and then cooled to -78° C. A solution of acrylate 20-5 (0.485 g, 1.76 mmol) in THF (5 mL) was added. After stirring for 15 min at -78° C., satd aq NH4Cl soln (5 mL) was added and the cold bath removed. The mixture was warmed to room temperature, and extracted with Et2O (2×40 mL). The combined organic extracts were washed with brine (30 mL), dried over MgSO4, filtered, and concentrated. The residue was purified by flash chromatography (40% ethyl acetate/hexanes) to give the β-aminoester 20-6 as a yellow oil.
