Tiadinil can be obtained through a multi-step reaction starting from a beta-ketoester. This is converted with an N -acetylated hydrazine to a hydrazone, which is cyclized with thionyl chloride and then hydrolyzed. After further conversion to the acid chloride , tiadinil is formed by reaction with 3-chloro-4-methylaniline .
