Reaction Steps

To a solution of 100 mg (0.52 mmol) 5-(o-hydroxyphenyl)-2-methyl-2-pentanol in 2 ml chloroform is added 25 mg (25 wt %) of p-tosic acid in one portion. The resulting solution is then heated at 80° C. for 2 hours. The reaction mixture is then diluted with methylene chloride and washed with a sat. solution of sodium bicarbonate. The organic layer is dried (MgSO4), filtered and concentrated to obtain 2,2-dimethyl-2,3,4,5-tetrahydro-1-benzoxepin which is used directly in the next step.
