实验步骤: To a solution of N-(4-chloro-3-methoxybenzyl)phthalimide (3.00 g) in ethanol (60 mL) was added hydrazine hydrate (2.62 mL), and the mixture was heated for an hour under reflux. The resulting precipitates were faltered off and the filtrate was evaporated in vacuo. The residue was partitioned between chloroform and an aqueous saturated sodium bicarbonate solution. The separated organic layer was washed with water and brine, dried over magnesium sulfate and evaporated in vacuo to give 4-chloro-3-methoxybenzylamine as a yellow oil (1.64 g). the mixture was heated for an hour under reflux The resulting precipitates the filtrate was evaporated in vacuo The residue was partitioned between chloroform The separated organic layer was washed with water and brine dried over magnesium sulfate evaporated in vacuo

实验步骤: To a mixture of (4-chloro-3-methoxyphenyl)methanamine (392 mg, 2.284 mmol) (as the hydrochloride salt), Hunig's Base (0.5 mL, 2.86 mmol), and MeOH (2 mL) was added a solution of methyl 2,2-diethoxyacetimidate (295 mg, 1.83 mmol) in MeOH (1 mL) and the resulting mixture was heated with stirring in an oil bath at 70° C. for 2 hrs and allowed to cool to room temperature over 3 days. The solvent was removed in vacuo and the residue was used without further purification. the resulting mixture was heated to cool to room temperature over 3 days The solvent was removed in vacuo the residue was used without further purification
