Continuously updated synthesis method about 18469-52-8

The synthetic route of 18469-52-8 has been constantly updated, and we look forward to future research findings.

18469-52-8, name is Methyl 4-(aminomethyl)benzoate, belongs to esters-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. name: Methyl 4-(aminomethyl)benzoate

Step 4. A solution of 5-fluoro-1H-indazole-3-carboxylic acid (0.25 g, 0.74 mmol) in dichloromethane (5.0 mL) was treated with triethylamine (0.083 g, 0.11 mL, 0.82 mmol), 4-dimethylamino pyridine (0.14 g, 1.1 mmol) and 1-(3-dimethylaminopropyl)-3-ethyl-carbodiimide hydrochloride (0.17 g, 0.89 mmol). 4-Aminomethyl-benzoic acid methyl ester (0.16 g, 0.82 mmol) was added. The mixture was stirred at room temperature for 16 hours, then partitioned between diethyl ether and 1N HCl. The organic phase was washed with water and brine, dried over magnesium sulphate and evaporated. The residue was purified by flash chromatography (heptane/ethyl acetate gradient), to yield 4-({[1-(4-difluoromethoxy-benzyl)-5-fluoro-1H-indazole-3-carbonyl]-amino}-methyl)-benzoic acid methyl ester as a yellow solid, 0.19 g (54%), m/z (ISP): 484.5 (M+H).

The synthetic route of 18469-52-8 has been constantly updated, and we look forward to future research findings.
