Participants

Reaction Steps

(S)-tert-Butyl 2-((1-(4-methoxy-2,6-dimethylphenylsulfonyl)-1,2,3,4-tetrahydroquinoline-2-yl)methoxy)acetate (1 g, 2.103 mmol) was dissolved in dichloromethane (15 ml) and trifluoroacetic acid (3.24 ml, 42.05 mmol) was added slowly. After stirring at room temperature for 2 h, the solvent was removed in vacuo and the residue was co-evaporated twice more with 20 ml of toluene each time. Yield: 0.84 g (95%).
