Ammonium Chloride → Methyl 4-(1-hydroxyethyl)-3-methoxybenzoate

Participants

Reaction Steps

To a mixture of methyl 4-formyl-3-methoxybenzoate (3.30 g) and THF (30 mL) was added dropwise methyl magnesium bromide (3 M diethyl ether solution, 3.60 mL) under ice-cooling. After dropwise addition, the mixture was stirred for 1 hour under ice-cooling. A saturated aqueous ammonium chloride solution was added thereto to stop the reaction, followed by extraction with ethyl acetate. The organic layer was washed with saturated brine, and then dried over an aqueous anhydrous sodium sulfate solution. The solvent was evaporated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain methyl 4-(1-hydroxyethyl)-3-methoxybenzoate (1.92 g).
