Reaction Steps
1 molar equivalent of o-(p-tolyl)-N-cyclohexylbenzaldimine is dissolved in a 1/1 mixture of tetrahydrofuran/water and X molar equivalents of aminohydroxysulphonic acid are added. This mixture is maintained at a temperature T for 1 hour, which gives a mixture of OTBO/OTBN. This mixture is diluted in tetrahydrofuran, 10 molar equivalents of phosphorus pentoxide are then added and the mixture is allowed to react for a further 1 hour at room temperature.
