Versuchsvorschrift
To a solution of (+1-) ethyl 4-[(5,5-dimethyl-8-hydroxy-5,6,7,8-tetrahydronaphthalen-2-yl)azo]benzoate (Compound D5, 49.7 mg, 0.141 mmol) in 4 ml of dry CH2Cl2 at 0° C. was added isopropyl ethyl amine (0.152 ml, 0.847 mmol) followed by chloromethyl methyl ether (0.0323 ml, 0.423 mmol). The reaction mixture was stirred at room temperature for 12 h. Solvent was removed under reduced pressure, the residue was dissolved in ethyl acetate and the solution was washed with NaHCO3 (sat.), and brine. The organic layer was dried (MgSO4). The solvent was removed under reduced pressure, the residue was purfied by flash chromatography (silica, ethyl acetate:hexane, 1:3) to afford the title compound as a red oil.
