Reaction Steps

26 mg of [1-(2,4-dimethoxy-benzyl)-2-oxo-1,2,5,6-tetrahydro-pyridin-3-yl]-acetic acid methyl ester (o) (0.08 mM) was dissolved in methanol solution under Ar atmosphere. 1.7 mg of 10% Pd—C was added thereto and the mixture was hydrogenated under a hydrogen balloon. The reaction mixture was stirred for 5 hrs at room temperature, filtered and concentrated in vacuo. The resulting compound was purified with Silica gel column chromatography to give 25 mg of [1-(2,4-dimethoxy-benzyl)-2-oxo-piperidine-3-yl]acetic acid methyl ester (r) (yield: 99%).
