Procedure

2.7 g of 1-methylpiperazine are added slowly to a suspension of 10.2 g of 5-[N-(1-adamantyl)-sulfamoyl]-isatoic anhydride in 250 ml of absolute toluene, at 100° with stirring. After the addition is ended, the mixture is stirred for a further 1 hour at 100° and is allowed to cool to room temperature, the precipitate is separated off by decanting and the crude product thus obtained is recrystallised from ethanol. 5-[N-(1-Adamantyl)-sulfamoyl]-anthranilic acid (4-methyl)-piperazide with a melting point of 214°-215° is obtained. (Melting point of the hydrochloride: 298°-300°).
