Procedure

C-(6-Benzenesulfonyl-naphthalen-1-yl)-methylamine is prepared from 7-Benzenesulfonyl-3,4-dihydro-2H-naphthalen-1-one following the procedures of Examples 1 and 2. C-(6-Benzenesulfonyl-naphthalen-1-yl)-methylamine and 5,5-dimethyl-2-methylsulfanyl-hexahydro-pyrimidine hydrochloride are added to methylene chloride, and the reaction mixture is heated to gentle reflux until all of the solvent is evaporated. The reaction mixture is heated to 150° C. and then cooled. The resulting mixture is basified by dropwise addition of aqueous NaOH solution, and then purified by preparative liquid chromatography to give (7-benzenesulfonyl-naphthalen-1-ylmethyl)-(5,5-dimethyl-1,4,5,6-tetrahydro-pyrimidin-2-yl)-amine.
