丙-2-烯基 5-溴-2-羟基苯甲酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 5-bromosalicylic acid (10 g, 46 mmol), allyl bromide (6.12 g, 51 mmol) and sodium bicarbonate (4.65 g, 55 mmol) in 50 ml of DMF was stirred under a drying tube for 72 hr. The reaction mixture was poured into water, extracted with ethyl acetate. and the organic layer dried over MgSO4. Concentration under vacuum gave 10.73 g (91%) of product (1-Scheme 2) with the expected NMR. extracted with ethyl acetate and the organic layer dried over MgSO4 Concentration under vacuum
