Synthesis
16665-38-6
16744-81-3
The general procedure for the synthesis of 4-methoxypyridin-2-aldehyde from (4-methoxypyridin-2-yl)methanol was as follows: - Manganese(IV) oxide (2.412 mL, 139.42 mmol, 4 eq.) was added batchwise to a solution of (4-methoxypyridin-2-yl)methanol (4.85 g, 34.85 mmol, 1 eq.) in ethyl acetate (150 mL). - The reaction mixture was stirred at 80 °C for 2 hours. - Upon completion of the reaction, the hot reaction mixture was filtered through diatomaceous earth. - The filtrate was evaporated to dryness to afford the target product 4-methoxypyridine-2-aldehyde (3.01 g, 21.93 mmol, 62.9% yield). 1H NMR (400.132 MHz, DMSO) δ 3.93 (3H, s), 7.27 (1H, m), 7.44 (1H, d), 8.63 (1H, d), 9.96 (1H, s).
