The invention relates to a method for preparing Crisaborole of Formula I, comprising using m-methylphenol as the starting material to obtain a target product through a five-step reaction. The starting materials and the raw materials used in each step of the method according to the present invention are cheap and easy to obtain, and the process is simple. The reaction of introducing boron atoms into the benzene ring to form an oxygen boron heterocycle is novel, with high yield and mild conditions, and is suitable for industrial production.
