Reaction Steps
To a suspension of LiAlH4 (4.64 g, 123.0 mmol) in dry THF (500 mL) was added 2-methyl-2-phenyl-propionic acid (20.0 g, 123.0 mmol) in dry THF (250 mL) dropwise at 55° C. over 10 min. The mixture was quenched with sodium hydroxide aqueous solution (60 mL, 15%). The mixture was filtered and the filtrate was dried over anhydrous sodium sulfate, filtered and evaporated to yield 2-methyl-2-phenyl-propan-1-ol (13.3 g, 72.7%), which was used to the next step without further purification.
