6-Methyl-2-pyridinecarboxaldehyde Use and Manufacturing
A solu-tion of 10.47 g (0.081 mol) of selenous acid in 30 mL of water was added with stirring to a solution of 20 g (0.162 mol) of (6-methylpyridin-2-yl)methanol (3a) in 150 mL of 1, 4-dioxane, and the mixture was stirred for 6 h at 100°C. Metallic selenium was filtered off, the solvent was distilled off from the filtrate under reduced pressure, and the residue was treated with hot hexane (3 × 150 mL). The solvent was distilled off from the combined extracts under reduced pressure, and the product was not purified additionally. Yield 14.76 g (0.121 mol, 75percent), mp 3133°C. 1 H NMR spectrum (DMSO-d 6 ), δ, ppm: 2.61 s (3H, Me), 7.49 d (1H, 5-H, J = 7.5 Hz), 7.71 d (1H, 3-H, J = 7.5 Hz), 7.86 d.d (1H, 4-H, J = 7.5, 7.5 Hz), 9.93 s (1H, CHO). Mass spectrum: m/z 122.06 (I rel 100percent) [M + H] + . Calculated: M 122.06.
6-Methyl-2-pyridinecarboxaldehyde was used in the synthesis of 1-(10-cyano- and -10-bromo-5H-dibenzo[a,d]cyclohepten-5-yl)-4-[(arylmethylene)amino]piperazines which are compounds that exhibits anticonvulsant properties.
