Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 5111-65-9, name is 2-Bromo-6-methoxynaphthalene, This compound has unique chemical properties. The synthetic route is as follows., name: 2-Bromo-6-methoxynaphthalene
Step 21.2: 6-methoxy-naphthalen-2-ylamine A solution of 2-bromo-6-methoxy-naphthalene (237 mg, 1 mmol), Pd (dba)2 mg, 0.05 mmol), tri-t-buthylphosphonium tetrafluoroborate (14 mg, 0.05 mmol), and lithium bis (trimethylsilyl)amide (1 M in hexane, 1.1 mL, 1.1 mmol) is stirred in toluene (2.5 mL) under argon for 6 h. The reaction mixture is taken in diethyl ether (20 mL), and quenched with 1 M HCI. The organic phase is extracted with water, the combined aqueous phases are treated with 1 M sodium hydroxide and extracted with DCM. The combined organic phases are dried over magnesium sulfate, the solvent is evaporated in vacuo and the residue is purified by column flash chromatography on silica gel (ethyl acetate) to afford 6-methoxy- naphthalen-2-ylamine (110 mg, 64 %), HPLC tR : 3.07, (M+H) + = 173.9.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 5111-65-9.
