Procedure

As described for example 112a, (6-methyl-2-oxo-2H-pyridin-1-yl)-acetic acid ethyl ester (Petride, Horia; Raileanu, Dan. Revue Roumaine de Chimie (1988), 33(7), 729-39.) in ethanol was reacted with hydrazine hydrate (1.8 equivalents) at rt for 96 h. The mixture was concentrated and crystallized from ethanol/diisopropylether and the compound was obtained as a white solid (yield: 88%). MS: m/e=204.2 [M+Na]+.
