Reaction Conditions

Reaction Steps

To a solution of tert-butyl 1,2,3,4-tetrahydroquinolin-3-ylcarbamate (248 mg, 1.0 mmol) and 2,4-difluorobenzaldehyde (300 mg, 2.11 mmol) in 1,2-dichloroethane (10 mL) was added tetramethylammonium triacetoxyborohydride (0.6 g, 2.0 mmol). The mixture was stirred at 50° C. for 20 hours. The mixture was quenched by addition of saturated Rochelle's salt (10 mL) and extracted with dichloromethane (3×10 mL). The combined organic layers were washed with water (2×10 mL), dried over anhydrous sodium sulfate and evaporated to dryness. The residue was purified by chromatography on silica gel (5-40% EtOAc/Hexane) to give tert-butyl 1-(2,4-difluorobenzyl)-1,2,3,4-tetrahydroquinolin-3-ylcarbamate (365 mg).
