Reaction Steps
To a solution of 5′-Methoxy-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid ethyl ester (0.17 g, 0.64 mmol) in 5 mL of THF/MeOH/H2O (1/1/1) was added LiOH.H2O (54 mg, 1.28 mmol). After 3 hours, the reaction was concentrated under vacuo, taken up in EtOAc, washed with aq. NH4Cl. The organic phase was dried over Na2SO4, and concentrated under vacuo to yield 60 mg (39%) of the title product as a light brown solid. ES-MS m/e: 235.1 (M−H+).
