(3) 1,3,5-triazines having the general formula (III’) depicted below:1
Formula (III’)
(SX 2003, col. 2, line 55 to col. 3, line 53). Shiokawa ‘146 provides three examples, Examples 5-7,
describing the preparation of 1,3,5-triazine intermediate compounds that fall within the scope of general
formula (III’). (SX 2003, col. 17, line 26 to col. 18, line 43).
7. Shiokawa ‘146 provides four examples of the preparation of compounds of the invention. In
particular, Example 1 describes the preparation of a 3-cyanoiminomorpholine heterocyclic intermediate
compound and the subsequent formation of 4-(2-chloro-5-pyridylmethyl)-3-cyanoiminomorpholine.
Example 2 describes the preparation of 5-methyl-2-nitroimino-hexahydro-1,3,5-triazine. Example 3
describes the preparation of 5-methyl-2-cyanoimino-hexahydro-1,3,5-triazine. Example 4 describes
the preparation of 1-(2-chloro-5-pyridylmethyl)-5-methoxy-2-nitroimino-hexahydro-1,3,5-triazine.
1The term “1,3,5-triazine” refers to a six-membered ring bearing three nitrogen heteroatoms,
the ring being in its fully unsaturated form, i.e., the ring contains three double bonds. (Nomenclature of
Organic Chemistry, IUPAC, SX 2097, p. 54). As the attorneys and experts for both Shiokawa and
Maienfisch have adopted the term 1,3,5-triazines as shorthand for the fully saturated hexahydro-1,3,5-
triazines, we will follow the parties lead and likewise adopt the term “1,3,5-triazines” as shorthand for
the compound hexahydro-1,3,5-triazine. (Shiokawa Motion 13, Paper No. 102, p. 7, fn. 4 and SX
2096, p.4, fn. 3).
