Reaction Steps

A solution of 146 g. (1.00 mole) of 1-tetralone and 150 ml. of piperidine in 1 l. of toluene is treated with 1 g. of p-toluenesulfonic acid and heated for 11 days under reflux with a water take-off trap attached. 13.1 ml. of water is collected. Fractional distillation affords 105.3 g. of 1-piperidino-3,4-dihydronaphthalene collected at 118°-120° (0.2 mm.).
