Procedure

Add 570 mg of powdered potassium hydroxide to 856 mg of the compound of Example 42 dissolved in 10 ml of acetone. Stir for 5 minutes and then add 0.14 ml of methyl iodide. After 15 minutes at room temperature, dilute the reaction mixture in 100 ml of dichloromethane, and then wash with water and with water saturated with sodium chloride. Dry the organic phase over sodium sulphate, evaporate to dryness and then subject the residue to chromatography on a silica column, using a mixture of cyclohexane and ethyl acetate (1:1 V/V) as eluent.
