Methanol → Methyl 4-(4-iodophenyl)butanoate

참여 물질

반응 단계

To a solution of 4-(p-iodophenyl)-butyric acid (45.0 g, 0.155 mol) in methanol (1.3 L), was added sulfuric acid (concentrated, 8.4 mL) dropwise and it was stirred at room temperature under nitrogen for 3 hours. The reaction mixture was concentrated on a rota-vapor, the residue was then partitioned between ethyl acetate (700 mL) and saturated sodium bicarbonate aqueous solution (500 mL). The organic phase was separated, washed with brine (2×200 mL), then dried over Na2SO4 and filtered. Evaporation of solvent gave the titled compound as an oil that was used in step B without further purification.
