Procedure
To a suspension of the compound of Example 1 (120 mg, 0.6 mmol) and caesium carbonate (731 mg, 1.8 mmol) in acetone (4 ml), under nitrogen, was added chloromethyl propionate (Eur. J. Pharm. Sci: 24; 5; 2005; 433-440, 183 mg, 1.5 mmol) and the reaction mixture was stirred at room temperature for 18 h. The mixture was filtered and the filtrate was concentrated in vacuo.
