1569-16-0, 2-Methyl[1,8]-Naphthyridine is a naphthyridine compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Step 5 2-methyl-5,6,7,8-tetrahydro-1,8-naphthyridine The compound was prepared according to the procedure as described in WO 0033838. To a solution of 2-methyl-1,8-naphthyridine (2 g, 13.9 mmol) in ethanol (35 ml) was added 10percent Pd/C, and the reaction mixture was stirred under H2 (10 psi) for 24 hours. Palladium was filtered out through celite and washed with excess ethanol. The filtrate was concentrated under vacuum to give 1.7 g (83percent) pink solid. NMR (CD3OD) delta 1.82-1.87 (m, 2H), 2.22 (s, 3H), 2.65-2.76 (m, 2H), 3.33-3.36 (m, 2H), 6.32 (d,1H, J=7.25 Hz), 7.07 (d, 1H, J=7.38 Hz). Mass spectrometry: 149.15 (M+H)+.
The synthetic route of 1569-16-0 has been constantly updated, and we look forward to future research findings.
