Procedure

The intermediate 3-methyl-4-phenylcyclohexanone is prepared, first by the reaction of 4-phenylcyclohexanone with phenylselenenyl chloride and aqueous 30% hydrogen peroxide, yielding 4-phenyl-2-cyclohexenone, and then the reaction of the cyclohexenone with 1.4M methyllithium and aqueous ammonium chloride, affording 3-methyl-4-phenylcyclohexanone. The cyclohexanone is then reacted with cyanoguanidine as previously described. Example 15 provides a detailed description of how this reaction is conducted.
