3.04 g (9.9 mmol) of the compound from Example 4A were dissolved in 100 ml of acetonitrile, and 1.07 g (9.9 mmol) of methyl chloroacetate, 2.73 g (19.8 mmol) of potassium carbonate and a small spatula tip of potassium iodide were added. The reaction mixture was heated under reflux for 1 h and then allowed to cool to RT and filtered. The filtrate was freed from the volatile components on a rotary evaporator and the residue was dried under high vacuum. This gave 3.70 g of the title compound in a purity of about 90%, (89% of theory).
