Synthesis

Butalamine has very similar synthesis but is alkylated on the alternate nitrogen position.

Thieme Patent[5]

The reaction of benzoylchloride oxime [698-16-8] (2) with Cyanamide (3) gives 3-Phenyl-1,2,4-oxadiazol-5-amine [3663-37-4] (4). Alkylation with 2-chlorotriethylamine [100-35-6] (5) in the presence of KOH base occurs at the endocyclic ring nitrogen completing the synthesis of imolamine (6).

EFforts towards Onepot method (section 2.5 & 2.6).
