Procedure

A mixture of C-(6-Benzenesulfonyl-naphthalen-1-yl)-methylamine, 2-methylsulfanyl-3,5-dihydro-imidazol-4-one (prepared by the method reported by Chen et al., WO9736859) and sodium hydroxide in ethanol is heated to reflux, then concentrated under reduced pressure, diluted with ethyl acetate, and washed with aqueous sodium carbonate. The organic phase is dried (magnesium sulfate) and concentrated under reduced pressure to give 2-[(6-benzenesulfonyl-naphthalen-1-ylmethyl)-amino]-3,5-dihydro-imidazol-4-one.
