Reaktionsschritte

A solution of 3.6 g (0.02 moles) of the triol of Example 1 in 50 ml. of benzene, and 1.5 g of butanal in the presence of 0.1 g p-toluene sulfonic acid are mixed together and stirred for several hrs. Water is removed by azeotropic distillation and the residue is taken to dryness to yield 06, 07 -butylidene - 5,6,7,8-tetrahydro-1,6,7-naphthalene triol.
