Sodium Hydroxide → HCID 19348623, compound

Participants

Reaction Steps

A solution of 32.19 g (0.101 mol) of methyl 4-(t-butyldimethylsilyl-oxymethyl)-2-methoxybenzoate (prepared as described in Preparation 39) in 50 ml of tetrahydrofuran was added dropwise to an ice-cooled suspension of 3.51 g (92.5 mmol) of lithium aluminum hydride in 250 ml of tetrahydrofuran over a period of 30 minutes. The resulting mixture was then stirred at the same temperature for 1 hour and then at room temperature for 40 minutes. At the end of this time, the reaction mixture was again cooled with ice, and 3.5 ml of water were added to the mixture to terminate the reaction. 3.5 ml of a 15% w/v aqueous solution of sodium hydroxide and 10.5 ml of water were then added, with stirring, to the mixture. Anhydrous magnesium sulfate was added, and the reaction mixture was filtered. The filtrate was freed from the solvent by distillation under reduced pressure, to give 29.30 g (a quantitative yield) of the title compound.
