Ethyl Acetate → 3-[(Octahydroquinoline-1-carbonyl)amino]propionic acid methyl ester

Participants

Reaction Steps

0.5 g (3.5 mmol) of the 3-aminopropionic acid methyl ester hydrochloride are dissolved in 5 mL of anhydrous THF and 0.9 mL of Et3N. Once dissolved, 650 mg of 1-chlorocarbonyloctahydroquinoline are slowly added and it is refluxed for 18 h. AcOEt is then added and the resulting solution is sequentially washed with water, 1N HCl and brine. The organic phase is dried over anhydrous Na2SO4, it is filtered and the solvent is evaporated under reduced pressure yielding 580 mg of intermediate IIIb.1.
