Reaction Steps
In a four necked round bottomed flask, 500 gm of (R)-2-chloromandelic acid was taken in 2600 ml methanol. Then 18.8 gm of sulfuric acid was added and heated to reflux, till completion of reaction. Then excess of methanol was distilled off under reduced pressure. Residue was taken in dichloromethane and washed with aqueous sodium bicarbonate solution. Dichloromethane was distilled under reduced pressure to obtain 522 gm of Methyl-(R)-2-hydroxy-2-(2-chlorophenyl)acetate as an oil. Yield: 94%. Purity: 98.5%
