A compound that can be converted, at a low cost and in a simple way, into 2-aryl-1,3-propanediols serving as precursors for synthesizing felbamate acting as an antiepileptic has a structure represented by Formula (1):
wherein Ar represents an aryl group; R¹ represents a hydrogen atom or is R⁴ or R⁵, where R⁴ represents an alkoxy group having 1 to 10 carbon atoms and R⁵ represents a hydroxy group or an acyloxy group having 1 to 10 carbon atoms; and R² and R³ are hydrogen atoms at the same time or R² and R³ together form a group represented by Formula (2):
wherein R⁶ and R⁷ each independently represent a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, or R⁶ and R⁷ together form an oligomethylene group having 2 to 10 carbon atoms.
