2-methylsulfanyl-1,4-dihydroimidazol-5-one

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of N-(5-Aminomethyl-5,6,7,8-tetrahydro-naphthalen-2-yl)-benzenesulfonamide, 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 N-{5-[(5-Oxo-4,5-dihydro-1H-imidazol-2-ylamino)-methyl]-naphthalen-2-yl}-benzenesulfonamide. 5-[(5-Oxo-4,5-dihydro-1H-imidazol-2-ylamino)-methyl]-naphthalene-2-sulfonic acid phenylamide may be similarly prepared. prepared by the method is heated to reflux concentrated under reduced pressure diluted with ethyl acetate washed with aqueous sodium carbonate The organic phase is dried (magnesium sulfate) concentrated under reduced pressure

Conditions: temp:0.00; pressure:0.00; stir:
