As a common heterocyclic compound, it belongs to naphthyridine compound, name is 2-Methyl[1,8]-Naphthyridine, and cas is 1569-16-0, its synthesis route is as follows.,1569-16-0
A mixture of 2-methyl-1,8-naphthyridine (18.5 g, 128 mmole), 10percent Pd/C (5 g), and absolute EtOH (150 mL) was shaken under hydrogen (15 psi) on a Parr apparatus. After 24 hr, the mixture was filtered through celite.(R)., and the filter pad was washed sequentially with absolute EtOH and EtOAc. The filtrate was concentrated to dryness to leave the title compound (18.85 g, 99percent) as an off-white solid: 1H NMR (300 MHz, CDCl3) delta 7.02 (d, J = 7.5 Hz, 1 H), 6.34 (d, J = 7.5 Hz, 1 H), 4.80 (br s, 1 H), 3.38 (m, 2 H), 2.74 (m, 2 H), 2.30 (s, 3 H), 1.88 (m, 2 H); MS (ES) m/e 149 (M + H)+.
With the complex challenges of chemical substances, we look forward to future research findings about 2-Methyl[1,8]-Naphthyridine
