Procedure

To a solution of 4.80 g (11.82 mmol) of the product of Example 17 dissolved in 5.0 mL of DMF was added 2.04 g (12.41 mmol) of 3-picolyl chloride hydrochloride and 4.89 g (35.46 mmol) of potassium carbonate. The reaction mixture was then stirred at room temperature for 18 h, diluted with water and extracted with ether. The oragnics were then extracted with 6N HCl solution and the aqueous acid layer was then basified with 6N NaOH solution and then extracted with ether. The resulting ether layer was dried over sodium sulfate, filtered and concentrated in vacuo to provide 4.16 g (71%) of the desired product as a tan solid. Electrospray Mass Spec: 498 (M+H).
