Reaction Steps
1,5-Naphthyridine was prepared from 3-aminopyridine according to the method descried in J. Org. Chem., 1963, 1757 and was isolated as colourless needles from n-hexane m.p. 69°C (lit. 74°). 1,5-Naphthyridine 2.6 g.) was hydrogenated in 95% ethanol over PtO2 catalyst under atmospheric conditions to give 1,2,3,4-tetrahydro-1,5-naphthyridine as colourless needles (2.51 g.).
