Methyl 2-(1,2,3,4-tetrahydroquinolin-6-yl)acetate synthesis

2synthesis methods
-

Yield:-

Reaction Conditions:

with palladium 10% on activated carbon;hydrogen in ethanol at 50; under 1551.49 Torr; for 12 h;

Steps:

35.1 Step 1. methyl 2-(1.2.3.4-tetrahvdroquinolin-6-yl)acetate

To a solution of methyl 2-(quinolin-6-yl)acetate (700 mg, 3.30 mmol) in ethanol (20 mL) was added Pd/C (400 mg, 0.376 mmol)(10%), and the reaction was stirred at 50 °C under 30 psi of hydrogen. The reaction was monitored by LCMS. After stirring for 12 h the reaction was finished. The catalyst was removed off by filtration, and the filtrate was concentrated in vacuo to give the title compound as an oil. LCMS m/z (M+H+) calc'd 206.1, found 206.0
