반응 단계
40 g of cyclopentene are added dropwise at 120° C to 148 g of 1-hydroxytetraline and 10 g of p-toluene sulphonic acid. The catalyst is removed by washing with sodium hydrogen carbonate solution. The reaction mixture is fractionated. At 161° C (2 mm Hg) 58 g of 1-hydroxy-2-cyclopentyltetraline are obtained.
