Reaction Steps
To a solution of valine tert-butyl ester hydrochloride (1.5 g, 7.15 mmol) in EtOH (10 mL) was added triethylamine (2.09 mL, 15 mmol), followed after 10 minutes by 2-nitrobenzyl chloride (1.227 g, 7.15 mmol). The mixture was then stirred for 20 h under reflux before it was evaporated. The residue was purified by flash chromatography (petrol/ethyl acetate, 85/15) to afford the sub-title compound as a colorless oil (1.753 g, 80%). 1H NMR (400 MHz CDCl3) δ 0.93 (6H, m), 1.48 (9H, s), 1.83-1.96 (2H, m), 2.82 (1H, d), 3.92 (1H, d), 4.11 (1H, d), 7.39 (1H, t), 7.57 (1H, t), 7.65 (1H, d), 7.89 (1H, d).
