YieldReaction ConditionsOperation in experiment
30% [0322] A solution of dinitrile in 38 mL of H2S04 and 22 mL of H20 was stirred at 135 °C for 13 h. The temperature was decreased to 95 °C and 75 mL of MeOH was added. After 1.5 h the solution was poured into another flask and cooled to 0 °C to -5 °C. A NaOH solution (29.0 g (725mmol) of NaOH in 75 mL of water) was added dropwise with stirring to pH=l. Solid NaHC03 and H20 were added to pH = 5-7. The aqueous layer (mixture) was extracted with EtOAc and layers were separated. The mixture was roughly filtered through a cotton plug, EtOAc was added to the aqueous layer, and the layers were separated. The combined extracts were dried over Na2S04, filtered, and concentrated. Some of the crude product was loaded onto a loading cartridge, and the rest of the mixture was filtered through Celite with CH2C12, concentrated, and loaded onto a loading cartridge. Purification by flash silica gel chromatography (CombiFlash) (20percent EtOAc/hexanes) provided 2.15 g of the dimethyl 4- hydroxyisophathalate as a pale yellow solid in about 30percent yield.
