Procedure

5,6,7,8-tetrahydro-4-bromo-2-naphthol (7 g, 30.8 mmol; step c) in example 29) is dissolved in dry acetone (100 ml) and treated with K2CO3 (15 g, 0.11 mol) and methyliodide (7.25 ml, 0.13 mmol). The reaction mixture is kept at RT over night. After filtration and removal of the solvent the residue is purified over silica gel (methylene chloride/cyclohexane 1/1) affording the compound as a white solid.
