実験手順

Add bromoethyl pyruvate (40 mL, 0.29 mol) to a solution of 1,2,3,4-tetrahydroquinoline (75.5 mL, 0.59 mol) in tetrahydrofuran (300 mL) dropwise over 30 minutes. Stir for 24 hours, filter the reaction mixture, rinse the filter cake well with tetrahydrofuran (100 mL), and concentrate the filtrate under reduced pressure to provide the desired compound as a red oil (79.7 g).
