実験手順

To a solution of 1-(4-(diethoxymethyl)phenyl)-N,N,-dimethylmethanamine (1.0 g, 4 mmol) in methanol (5 mL), a hydrochloric acid-methanol solution (10 mL) was added dropwise at 0° C. The reaction solution was stirred at room temperature overnight. Then methanol was removed in vacuo to give 4-((dimethylamino)methyl)benzaldehyde (0.68 g, yield 99%) as a light yellow oil. 1H-NMR (400 MHz, CDCl3): δ 2.26 (s, 6H), 3.50 (s, 2H), 7.49 (d, J=6.4 Hz, 2H), 7.84 (d, J=6.4 Hz, 2H), 10 (s, 1H). LC-MS (ESI) m/z: 164 (M+1)+.
