Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 81335-87-7, name is (2-Amino-4-methylphenyl)methanol. A new synthetic method of this compound is introduced below., SDS of cas: 81335-87-7
General procedure: A test tube (25 mL) wascharged with 2-aminobenzyl alcohol 1 (0.5 mmol, 1equiv), alkynes 2 (0.75 mmol, 1.5 equiv), AgOTf (0.025 mmol, 5 mol %), HOTf (0.05mmol, 10 mol%), LiBr (0.05 mmol, 10mol%), H2O (0.2 mL), and toluene (3 mL) were added. Themixture was stirred at 40 oC in air for 8 hours, the reaction wascooled down to room temperature, the mixture was quenched by sat. aq. NaHCO3,and diluted with 10 mL dichloromethane and washed with 10 mL H2O.The aqueous layer was extracted twice with dichloromethane (10 mL) and thecombined organic phase was dried over Na2SO4. Afterevaporation of the solvents, the residue was purified by silica gelchromatography (hexane/AcOEt = 30:1).
