实验步骤: To a solution of 4-methoxy-3-(2-methoxyethoxy)benzaldehyde (10 g) in AcOH (80 mL) was added KOAc (9.5 g) and NH2OH.HCl (6.7 g). The resulting mixture was heated at 130° C. for 18 h under N2 atmospheres. After reaction finished, the mixture was poured into water (400 mL). The solid was collected, washed with water (100 mL) and air-dried to give 4-methoxy-3-(2-methoxyethoxy)benzonitrile (8.8 g) as a light yellow solid. After reaction The solid was collected washed with water (100 mL) air-dried

反应条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 3-hydroxy-4-methoxybenzaldehyde (8.0 g) in DMF (60 mL) was added K2CO3 (8.0 g) and 1-chloro-2-methoxyethane (5.1 g). The resulting mixture was stirred at 80° C. overnight. After reaction finished, ethyl acetate (200 ml) was added, and washed with 2 N aqueous HCl solution, brine, dried over Na2SO4, filtered, concentrated. The residue was washed with petrol ether to give 4-methoxy-3-(2-methoxyethoxy)benzaldehyde (11 g) as a yellow solid. 1H-NMR (400 MHz, CDCl3): δ: 9.84 (s, 1H); 7.49-7.43 (m, 2H); 6.98 (d, J=8.0, 1 H); 4.25-4.22 (m, 2H); 3.95 (s, 3H); 3.83-3.81 (m, 2H); 3.46 (s, 3H). After reaction washed with 2 N aqueous HCl solution, brine dried over Na2SO4 filtered concentrated The residue was washed with petrol ether
