Versuchsvorschrift
A solution of the product from step (c) (40.2 g), potassium carbonate (46.5 g) and methyl iodide (20.9 ml) in dry dimethylformamide (150 ml) was stirred at 20° C. for 16 hours. The solvent was evaporated and the residue quenched with water. The aqueous phase was extracted with ethyl acetate which was washed with brine, dried, filtered and evaporated to leave a yellow oil (27.4 g), MS; m/e 283.
