Versuchsvorschrift

A solution of the title compound from step 1 (11.6 g, 50.0 mmol) in abs. dichloromethane (200 mL) was mixed with tert-BuOK (6.50 g, 58.0 mmol) and methyl iodide (3.42 mL, 55.0 mmol) at 0° C. in argon. After 30 min the batch was heated to RT and then stirred overnight (solid separated out). The reaction mixture was washed with water and saturated NaCl solution (50 mL), dried over Na2SO4, concentrated to low volume in a vacuum and the remaining residue purified by flash chromatography with ethyl acetate/MeOH 20:1.
