Reaction Steps

The pyridinium p-toluenesulfonate was prepared by swirling 17.1 g (90 mmoles) of p-toluenesulfonic acid monohydrate with 36 ml (450 mmoles) of pyridine at ambient temperature in a 100-ml round-bottomed flask for 20 minutes. Excess pyridine was removed in a rotary evaporator. White crystals formed which were dried in a vacuum oven overnight at 80°. The yield was 21 g (84%), m.p. 120°.
