Procedure
1-(1-Aminomethylcyclohexyl)-4-methylpiperazine (0.5 g) was added to 10% sodium hydroxide solution (10 ml) and p-toluene sulphonyl chloride (0.5 g), and the mixture shaken vigorously. The solid was filtered, washed with water and recrystallised from 95% ethanol to give colourless needles (0.4 g, 46.2%) of 1-(1-tosylaminomethylcyclohexyl)-4-methyl piperazine, m.p. 128°-130°.
