Procedure
As described for example 112a, (4,6-dimethyl-2-oxo-2H-pyridin-1-yl)-acetic acid ethyl ester (Shusherina, N. P.; Slavyanova, O. V.; Petrova, L. K.; Levina, R. Ya. Zhurnal Organicheskoi Khimii (1972), 8(2), 387-9) in ethanol was reacted with hydrazine hydrate (1.2 equivalents) at rt for 120 h. The mixture was concentrated and crystallized from ethanol/diisopropylether and the title compound was obtained as a white solid (yield. 90%). MS: m/e=218.2 [M+Na]+.
