Procedure
40.00 g (210 mmol) 3-(2-oxo-imidazolidin-1-yl)-benzonitrile are suspended in 1500 ml of methanol, 53 ml of 37% hydrochloric acid are added. The mixture is hydrogenated for 20 hours at ambient temperature under a pressure of 7 bar with 4.00 g palladium/charcoal. The catalyst is filtered off, the filtrate is concentrated and the precipitate formed is suction filtered, washed with acetone and dried.
