DL-111-IT (CAS NO.: ), with its systematic name of 1H-, 3-(2-ethylphenyl)-5-(3-methoxyphenyl)-, could be produced through many synthetic methods.

Following is one of the reaction routes: Ethyl 3-metboxybenzimidate (I) is condensed with 2-ethybenzoic hydrazide (II) to produce benzoylamidrazone (III) in the presence of refluxing CH₂Cl₂, and then the yielding product is cyclized with K₂CO₃ in refluxing 2-etoxyethanol.
