Participants

Reaction Steps

Following the procedure of Example 1, step 2, 26.65 g (0.151 mol) of 5-hydroxy-5-methyl-6,7,8,9-tetrahydro-5H-benzocycloheptene in 300 ml of toluene was reacted with 0.30 g of p-toluenesulphonic acid monohydrate. Vacuum distillation yielded 19.17 g (80%) of the title product as a colourless oil, b.p. 62°-65° C./1.0 mm of Hg. NMR δ(CDCl3) 1.81 (2H, q, J=7.1 Hz), 2.07 (2H, m), 2.09 (3H, s), 2.56 (2H, t, J=6.9 Hz), 6.97 (1H, m), 7.14-7.26 (4H, m).
