The present invention relates to a process for synthesizing an anhydroecgonine derivative without using cocaine as a starting material, and a process for synthesizing a phenyltropane derivative by using said anhydroecgonine derivative as an intermediate for the synthesis. The present invention provides a process for synthesizing an anhydroecgonine derivative which comprises reacting a cycloheptatriene derivative represented by the formula (1):
1
with a primary amine, a salt thereof or ammonia in the presence of a base to obtain an anhydroecgonine derivative, and a process for synthesizing a phenyltropane derivative by using said anhydroecgonine derivative. In the formula (1), n is an integer of 0 or 1; and R
1
is a cyano group in the case of n being 0, and R
1
is selected from an alkyl group and an aralkyl group in the case of n being 1.
