Reaction Conditions

Reaction Steps

A Grignard reagent was previously prepared using 99.3 g of 1-tert-amyloxy-4-chlorobenzene, 12.76 g of magnesium, and 200 mL of tetrahydrofuran. To the Grignard reagent, 57.1 g of trimethyl borate was added dropwise at an internal temperature below −50° C. At a reaction temperature of 5° C., stirring was continued for 3 hours. Thereafter, at an internal temperature below 30° C., 45.0 g of acetic acid and 145.7 g of 35% hydrogen peroxide solution were added. At room temperature, stirring was continued for 3 hours. Standard work-up and purification by silica gel chromatography gave 62.2 g of 4-tert-amyloxy-1-phenol (yield 69%).
