实验步骤: Lithium aluminum hydride (5.21 g) was suspended in THF (243 ml). Then, a solution of the compound (24.3 g) obtained in Example 103-1 in THF (243 ml) was gradually added to the suspension over 50 minutes while stirring under ice-cooling, followed by stirring at room temperature for 1 hour. The reaction solution was added with sodium sulfate decahydrate and a 20% sodium hydroxide aqueous solution and then filtrated through Celite. The filtrate was concentrated under reduced pressure and dried under vacuum, thereby obtaining the subject compound (18.5 g). cooling by stirring at room temperature for 1 hour a 20% sodium hydroxide aqueous solution and then filtrated through Celite The filtrate was concentrated under reduced pressure dried under vacuum

实验步骤: A mixture of 16.2 g (64.5 mmol) of 4-(tert-butoxycarbonylaminomethyl)benzoic acid, 13.6 g (70.9 mmol) of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, 1.00 g of 4-dimethylaminopyridine and 200 ml of methanol was stirred at room temperature for 4 hours. Methanol was distilled off under reduced pressure and ice water was poured to the residue thus obtained. The mixture was extracted twice with ethyl acetate and the extract was washed with 10% citric acid aqueous solution and then with saturated sodium hydrogencarbonate aqueous solution and finally with saturated sodium chloride aqueous solution. After drying over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure to give 14.3 g (83.6%) of methyl 4-(tert-butoxycarbonylaminomethyl)-benzoate. Methanol was distilled off under reduced pressure and ice water was poured to the residue thus obtained The mixture was extracted twice with ethyl acetate the extract was washed with 10% citric acid aqueous solution After drying over anhydrous magnesium sulfate the solvent was distilled off under reduced pressure

实验步骤: 1.13 g of NaH at 60% in oil, and then 2.35 ml of methyl iodide are added to a solution of 5 g of methyl 4-[[(tert-butoxycarbonyl)amino]methyl]benzoate in 150 ml of THF and the mixture is left to stir at AT overnight. The reaction mixture is concentrated under vacuum, the residue is taken up with a water/ice mixture, the mixture is extracted with EtOAc, the organic phase is dried over Na2SO4, and the solvent is evaporated off under vacuum. The residue is taken up with 80 ml of 2N hydrochloric ether, 1 ml of water is added, and the mixture is left to stir at AT overnight. The reaction mixture is concentrated under vacuum, the residue is taken up with a 5% NaHCO3 solution, the mixture is extracted with DCM, the organic phase is dried over Na2SO4, and the solvent is evaporated off under vacuum. 2.2 g of the expected compound are obtained. the mixture is left The reaction mixture is concentrated under vacuum the mixture is extracted with EtOAc the organic phase is dried over Na2SO4 the solvent is evaporated off under vacuum is added the mixture is left to stir at AT overnight The reaction mixture is concentrated under vacuum the mixture is extracted with DCM the organic phase is dried over Na2SO4 the solvent is evaporated off under vacuum
