Preparation
4-Benzyloxyphenol Synthesis: Add 2.63g (0.028mol) of hydroquinone to a 100mL conical flask, weigh 1.12g (0.028mol) of sodium hydroxide, add 8mL of water, wait for the sodium hydroxide to dissolve and add dropwise to the conical flask with hydroquinone, shake well, then add 15mL of DMF and 2.52g (0.02mol) of benzyl chloride, under microwave radiation power of 320W The reaction was cooled to room temperature at the end of the reaction. The reaction was first adjusted to alkalinity with 10% sodium hydroxide, filtered, and the filtrate was washed with 10% sodium hydroxide until the filtrate was colorless (the filtrate was hydroquinone bis(benzyl ether), which could be recycled). The filtrate was acidified with hydrochloric acid to make Monobenzone completely precipitated, and then washed by filtration and ice water, recrystallized with alcohol and water, and decolorized by activated carbon to obtain 2.55g of white solid, the yield was 63.79%.
Indications
Monobenzone (Benoquin) potently inhibits melanin production and destroys melanocytes. Like hydroquinone, monobenzone was originally introduced for the topical treatment of disorders of excess melanin pigmentation, including melasma. It is now used only to permanently depigment the remaining normally pigmented skin in patients with extensive vitiligo. Irritant and allergic contact dermatitis are common side effects.
