Scheme 3 describes the preparation of known starting materials. The processes for preparation of these compounds are also known or may be carried out in analogous manner to known methods. For example, N-[(3-cyclopropyl-1,2,4-oxadiazol-5-yl)methyl]phthalimide is prepared by reaction of N-phthaloylglycine in DMF and 1,1′carbonyldiimidazole, and followed by the addition of cyclopropanecarboxamidoxime. The obtained N-[(3-cyclopropyl-1,2,4-oxadiazol-5-yl)methyl]phthalimide is then dissolved in 1,2-dichloroethane and N-methylhydrazine is added. The obtained 4-(aminomethyl)-3-cyclopropyl-1,2,4-oxadiazole is then treated with N,N-dimethylformaldehyde diethyl acetal and heated at about 130° C. and the desired starting material (E/Z)-N′-(3-cyclopropyl-[1,2,4]oxadiazol-5-ylmethyl-N,N-dimethyl-formamidine is obtained.
