Reaction Steps

To a solution of 1,2,3,4-tetrahydroquinoline (75.5 mL, 0.59 mol) in tetrahydrofuran (300 mL) was added bromoethyl pyruvate (40 mL, 0.29 mol) dropwise over 30 minutes. Following 24 hours of stirring, the reaction mixture was filtered, the filter cake rinsed well with tetrahydrofuran (100 mL) and the filtrate concentrated under reduced pressure to dryness to give 79.7 g of the desired compound as a red oil.
