Procedure
Thionyl chloride (15 ml) was added dropwise to a solution of 3-(4-hydroxy-3-nitrophenyl)propionic acid (49 g, 232 mmol) obtained in 1) above in methanol (500 ml), and the mixture was stirred overnight at room temperature. After, the reaction solution was concentrated, water (500 ml) was added to the reaction solution which was then extracted with ethyl acetate. The extract was washed with water and aqueous saturated sodium bicarbonate, dried over magnesium sulfate and concentrated, whereby methyl 3-(4-hydroxy-3-nitrophenyl)propionate (47 g) was obtained as powder.
